Ok so its mathematician. Whatever.

I need help. I'm really bad at math and I need to figure out a friend of mines throwing speed. She throws a softball 84 ft and 10.25 inches (home to second base) in 1.61 seconds. I need to convert that to miles per hour.

Bleh, use metric.

#3

Convert to metric or find me a converter and I'll help. Stupid America (I assume) and its retro measuring.

#4

This is America (for me)! We're to cool for the metric system regardles of its superiority lol

#5

Wouldn't know how to do it in imperial measurements without a converter, sorry.

#6

well, a quick google search reveals that 1 f/s= 0.6818mph

you start with about 84.85 feet in 1.61 sec which is about 52.7 feet per second, so about 35.9mph

for any conversion just search on google and it should tell you

#7

I'll guess 34.0324 mph.

#8

632.45 Mph.

i think you would divide 360 by 1.61 and than multiply the distance by that number...? and than whatever distance that is just convert it to miles and that should hopefully be mph

edit: if i had a calculator i woud do it for you but too bad for you, i dont

Velocity = distance/time.

but that only works for S.I. units (metres/second, metres, seconds). So yeah...this post was no help.

ok so i worked the speed out to be ROUGHLY 16m/s. So u gotta convert that to mph somehow

after consulting a speed converter, 15.9 meters/second = 35.567287043665 miles/hour

632.45 Mph.

that's probably a little high

#12

Nope. This is the pit. If 632.45 is too high, rub Icy Hot on it.

ok so you have the given factors of distance and time.....84.85 feet and 1.61 sec, divide those 2 to get 52.7 feet per second, now you just convert that.

ok so then you are trying to go feet/sec to miles/hour. 5280 feet in a mile, 3600 seconds in an hour. 1 foot/second is equal to (1/5280)mile/(1/3600)hour. that simplifies to 3600/5200 which is approximatley equal to 0.6818.

multiply 52.7 by the conversion rate of .6818 and you get 35.93

Thanks everyone Google says 35.9 and change miles per hour, but my mom says she (being Raven, not mom) throws way harder than that. Whatever though.

#15

I knew taking pre calculus last year would help someone somewhere along the line at some point in time

She threw 35.93485 mph.

She threw 35.93485 mph.

#16

I took pre-calc 2 years ago and it did nothing for me lol

Converting feet to miles:

__5280 ft__

84.84517ft

=0.016069 mi

Converting seconds to hours:

__1.61__

3600 s (1 hr)

=0.000447 hrs

Setting up the proportion:

__0.016069 mi__=

__x mi__

0.000447 hrs 1 hr

x ~ 35.948436

**OVERVIEW:**

First I converted the seconds and feet into miles and hours. Then I set up a proportion, if we were using the original terms it would have been:

__1.61 s__=

__x mi__

8.4851 ft 1 hr

Use cross multiplication, 1 hr x 1.61 s = 1.61s, divided by 8.4851 ft, makes x equal to approximately 35.95 miles per hour.

This answer is only approximate because i rounded off after four or five decimal places.

Hopefully it helped, I have nothing better to do so I figured I'd make it fancy for you

Did you hear about the constipated mathematician?

He had to work it out with a pencil!!!!!!!!!!

You're friend throws slow.

He had to work it out with a pencil!!!!!!!!!!

One day, there was a major nerd convention somewhere, and a Physicist, a chemist, and a Mathematician all want to go to it. They are all good friends, but are all broke, so they decide to share a single hotel room in one of the cheaper hotels in town.

Sometime in the middle of the night, the wiring in the hotel room begins to spark and starts a small fire. The physicist wakes up first. He sees the fire, and so somewhat groggily grabs a bucket (which I guess was just sitting around), goes to the faucet, fills the bucket, and puts the fire out. He then returns to bed.

A little while later, the wiring starts sparking again and there's another fire. This time the chemist wakes up. When he sees the fire, he examines it for a minute or two, and then measures out a precise molarity of water, fills the bucket, and then pours it on the fire, putting it out. He then returns to bed.

Soon enough, the fire starts again. The mathematician wakes up. As he sees the fire, he jumps out of bed, and quickly looks around the room. He sees both the bucket and the faucet.

He then returns to bed, satisfied that a solution exists.
