Question

345 ft/min = ___________ ft/h

Answer 1

`1h=60min\to1min=(1)/(60)h\\\\\\345\ ft/min=345\ (ft)/((1)/(60)h)=345*60\ ft/h=20,700\ ft/h`

Answer 2

the rate given is 345 ft/min

this means within 1 min distance is - 345 ft

we have to convert this speed to ft/h

1 hour is equivalent to 60 minutes

so if 60 minutes equals 1 hour

1 minute is equal to - 1/60 hr

so the distance within 1 minute is - 345 ft

since 1 min = 1/60 hr

distance within 1/60 hour = 345 ft

therefore distance in 1 hour =
`(345)/(1/60) = 345 * 60 = 20 700 ft`

answer is 20 700 ft/h
