Question

Yolanda drove 50 miles in 2 hours at a constant speed. Use a proportion to find how long it would take her to drive at 150 miles at the same speed.

Answer 1

It will take 6 hours.

Explanation:

Using proportions:

50 miles 150 miles

------------------ = -------------

2 hours x hours

Using cross products

50 * x = 2 * 150

50x = 300

Divide each side by 50

50x/50 = 300/50

x = 6

It will take 6 hours.
