Question

If Derek walks 6 miles in 80 minutes, then how far will Derek walk in 120 minutes?

A. 9 miles
B. 8.5 miles
C. 12 miles
D. 10.5 miles

Answer 1

Derek will walk 9 miles in 120 minutes.

Step-by-step explanation:

To solve this problem, we can set up a proportion to find the distance Derek will walk in 120 minutes. The proportion can be written as:

6 miles / 80 minutes = x miles / 120 minutes

To solve for x, we can cross multiply and then divide:

80x = 6 * 120

80x = 720

x = 720 / 80

x = 9

Therefore, Derek will walk 9 miles in 120 minutes.
