Question

The height of the snow was 84 inches in the beginning of the week. it melts at a rate of 0.15 inches per hour. how many hours would it take for the snow to reach 62 inches?

Answer 1

146.66 hours.

Explanation:

Given: Height of snow at the beginning is 84 inches.

Snow melting rate is 0.15 inches per hour.

Now, finding number of hours to reach 62 inches of snow.

First lets find the number of inches reduced.

Reduced inches of snow=
`84\ inches - 62\ inches= 22\ inches.`

∴ Reduced inches of snow is 22 inches after melting at 0.15 inches per hour.

Next finding hours to melt 22 inches of snow.

Time=
`(total\ size)/(melting\ rate)`

⇒ Time=
`(22)/(0.15) = 146.66\ hours`

Hence, 146.66 hours would it take for the snow to reach 62 inches.
