Question

Ross drives 340 miles in 5 hours. If Ross continues to drive at the same rate, how many miles can he drive in 10 hours?

Answer 1

Just Double 340 since 5 x 2 is 10! so 680 miles

Answer 2

Including the miles already driven: 680

Explanation:

1. We can see that 5 is half of 10, or 1/2.

2. Times 340 by 2 because he has has already driven 1/2 of the time needed, so he needs to drive another 5 hours in order to complete the 10 hours needed.

Or: 340 x 2 = 680.

3. So in 10 hours he will have driven 680 miles.
