Question

The distance traveled at a constant speed is directly proportional to the time of travel. If Olivia traveled 306 miles in 8.5 hours, how many miles will Olivia travel in 9.1 hours at the same constant speed?

A. 323.6 mi
B. 288.4 mi
C. 327.6 mi
D. 21.6 mi

Answer 1

C. 327.6 mi

Explanation:

Work out how far she can travel in one hour. If Olivia travels 306 miles in 8.5 hours, she will travel 306/8.5 miles in one hour.

`(306)/(8.5)` (Divide the two numbers)

306÷8.5=36 (
`(306)/(8.5)`=36)

Then multiply this by 9.1. Olivia travels 327.6 miles in 9.1 hours.

Answer 2

C is the correct answer. First, work out how far she can travel in one hour. If Olivia travels 306 miles in 8.5 hours, she will travel 306/8.5 miles in one hour - this equals 36 hours. Then multiply this by 9.1. Olivia travels 327.6 miles in 9.1 hours.
