Question

A family plans a road trip from Fairbanks to Newbury. The distance between the two cities is 240 miles when traveling on the highway. The family decides to take a new route, which they estimate will be 125% of the distance when traveling on the highway. There are approximately 48.28 kilometers in 30 miles. How many kilometers will the family drive on the new route? Round the answer to the nearest tenth. Enter the answer in the box.​

Answer 1

Using proportions, it is found that the family will drive 482.8 km on the new route.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the family travels a distance of 125% of 240 miles, hence the distance is:

D = 1.25 x 240 = 300 miles.

Since there are are approximately 48.28 kilometers in 30 miles, and 300/30 = 10, the distance in kilometers is given by:

D = 48.28 x 10 = 482.8 km.
