How many cups in a gallon? How many cups in 24 gallons?

How many seconds in a minute? How many seconds in 5 minutes?

Answered by Reiny
Why don't you type one of the examples that your teacher gave you in "chart format" so we can see what you need ?
Answered by sahsa to reiny
ok sure for example in this problem:

a worm moved 8 inches in five seconds. how many miles per hour is this?

8 in 1 ft 1 mile 60 sec 60 min
5 sec 12 in 5280 feet 1 minute 1 hour

then u cross out in and in then sec with sec ft with ft min and min then u are left wth miles on top and hour on bottom
so then what u do is the top is 8*1*1*60*60
and the bottom is 5*12*5280*1*1

so u multiply both which is
28800 miles
316800 hours
then divide
0.09 miles per hour

Wow, no wonder you guys are confused.
How to complicate a simple question !
It does work, but ......

"old-fashioned way"

8 inches per 5 second
= 96 inches/min
= 5760 inches/hour -- and there are 5280x12 or 63360 inches per mile
= (5760/63360) miles/hr
= .0909.. miles/hr
