Question

Walkers A and B are doing a charity relay race. Walker A starts by completing 6 miles, and then hands a

baton off to Walker B who walks another 6 miles. Using the graph below, determine how long will it take
Walkers A and B to complete their relay.

Answer 1

15.6 hrs

Explanation:

Walker A:

1.25 miles in 2.25 hrs

6/1.25 = 4.8

4.8×2.25 = 10.8

6 miles in 10.8 hrs

Walker B:

2.5 miles in 2 hrs

6/2.5 = 2.4

2.4×2 = 4.8

6 miles in 4.8 hrs

10.8 + 4.8 = 15.6
