Question

Samantha was driving down a road and after 4 hours she had traveled 70 miles. At this speed, how many hours would it take Samantha to drive 105 miles?

Answer 1

It would take Samantha 6 hours to drive 105 miles.

Explanation:

This question can be solved by proportions.

After 4 hours she had traveled 70 miles.

This means that she travels 70/4 = 17.5 miles per hour.

How many hours would it take Samantha to drive 105 miles?

17.5 miles per hour, so for 105 miles:

105/17.5 = 6

It would take Samantha 6 hours to drive 105 miles.
