Question

Angie is driving from the Tri-Cities to Salt Lake City. The total distance she will be traveling is 650 miles. After 4 hours, Angie stops at a gas station and notes she has traveled a total of 260 miles so far. At this rate, how many hours does Angie have remaining before she arrives at her destination?

Answer 1

Angie has 6 hours remaining before she arrives at her destination.

Explanation:

If Angie has traveled a total of 260 miles in 4 hours, her average speed was 65 mph (260/4). Thus, since Angie travels from the Tri-Cities to Salt Lake City, which are 650 miles away, the remaining distance for her is 390 miles (650 - 260). Therefore, maintaining her average speed of 65 mph, she has 6 hours (390/65) remaining before she arrives at her destination.
