Question

what conversion factors should be used to convert 18 mi/hr to ft/sec? what conversion factors should be used to convert 18 mi/hr to ft/sec? @Mathematics

Answer 1

1 mile = 5280 feet
1 hour = 60 seconds
so if you travel 18 miles in one hour
- that means you travelled (18*5280) feet in one hour
- which means you travelled (18*5280)/60 feet in one second

so conversion factor is 5280/60 = 88

Answer 2

oops!
1 hour = 3600 seconds

Answer 3

please correct my mistake when you do the calculation

Answer 4

so 5280/3600?

Answer 5

yes, which works out at 22/15

Answer 6

okay thank you! & do you know how to determine if each rate is a unit rate?

Answer 7

I am not sure I understand that question

Answer 8

like..

Answer 9

3 liters per 60 seconds

Answer 10

ah - ok - just looked up what that means, see: http://www.aaamath.com/rat-unit-rate.htm

so yes, this is a unit rate just like the original miles per hour was as well

Answer 11

the problem is, i have no idea how to solve these.
:/

Answer 12

by the way - 3 liters per 60 seconds would NOT be a unit rate
but I think 3 liters per minute would be
unless I have misunderstood the term

Answer 13

if you break the problem down into simple steps (as I did above) then you should be able to grasp it

Answer 14

that's what it says on the problem.

Answer 15

okayy.:)

Answer 16

but can you do this one so like i can have an example? :)

Answer 17

so 18 miles per hour = (18*22/15) feet per second = 26.4 ft/sec
