Question

A car travels 110 miles in 2 hours. At the same rate of speed, how far will the car travel in h hours? If rain is falling at the rate of 2 inches per hour, how many inches of rain will fall in x minutes?

Answer 1

Car will travel
`55h \ miles` in h hours.

Rain will fall
`(x)/(30) \ inches` in x minutes.

Explanation:

Speed of Car =
`(total \ distance)/(total \ time) =(110)/(2) =55 \ miles/hour`

Distance covered by car in x hour =
`speed \ * \ time=55 * h=55h\ miles`

Rain fall in 1 hour =
`2 \ inches`

Rain fall in
`60 \ minutes=2 \ inches`

So rainfall in
`1 \ minutes=(2)/(60) =(1)/(30) \ inches`

Rainfall in
`x \ minutes=(1)/(30) * x=(x)/(30) \ inches`
