Question

A hurricane traveled 180 miles in 4 hours. If the average rate at which the hurricane is moving slows by 10%, what is the distance that the hurricane will travel in the following 6 hours?

A. 330 miles
B. 297 miles
C. 243 miles
D. 210 miles

Answer 1

C!

Explanation:

10% of 180 is 18, and 180-18=162. 162/4= 40.5, and 40.5x6=243!

Answer 2

243 miles

Explanation:

A hurricane traveled 180 miles in 4 hours.

Hurricane traveled in 1 hour =
`(180)/(4)`

=
`45`

The average rate at which the hurricane is moving slows by 10%

So, Distance traveled by hurricane in hour after 10% slow rate =
`45-(10)/(100) * 45 =40.5`

The distance that the hurricane will travel in the following 6 hours =
`40.5 * 6 =243`

So, Option C is true

Hence the distance that the hurricane will travel in the following 6 hours is 243 miles
