Question

Wendy and Roger camped out at a state park, and then hiked back to their cars, which were

parked on opposite ends of the park. Wendy headed due north at 3 miles per hour, and Roger
hiked due south at 6 miles per hour. In how long were the two friends 2 miles apart?
If necessary, round your answer to the nearest minute.

Answer 1

Wendy and Roger were 2 miles apart for approximately 13 minutes.

Step-by-step explanation:

To find out how long Wendy and Roger were 2 miles apart, we need to determine the time it takes for them to cover a total distance of 2 miles (since they are moving in opposite directions). Since Wendy's speed is 3 mph and Roger's speed is 6 mph, the total speed at which they are moving apart is 3+6= 9 mph. We can use the formula:

Time = Distance / Speed

Substituting the values, we get:

Time = 2 miles / 9 mph = 0.22 hours.

To convert hours to minutes, we multiply by 60:

0.22 hours x 60 minutes/hour = 13.2 minutes. Therefore, Wendy and Roger were 2 miles apart for approximately 13 minutes.
