Question

In a small motorboat, Andrew traveled north on a river at 15 miles per hour (mph). After turning around, he motored back to his starting point along the same route at 25 mph. If the whole trip took 4 hours, how many miles did he travel before turning around?

Answer 1

To find the distance Andrew traveled before turning around, set up an equation using the times for each leg of the trip and solve for d.

Step-by-step explanation:

To determine the distance Andrew traveled before turning around, we need to find the time it took for each leg of the trip. Let's assume the distance Andrew traveled before turning around is represented by d.

For the first leg of the trip traveling north, Andrew traveled at a speed of 15 mph. The time it took for this leg is d/15.

For the second leg of the trip traveling south, Andrew traveled at a speed of 25 mph. The time it took for this leg is d/25.

Since the total trip took 4 hours, the combined time for the two legs is d/15 + d/25 = 4. Solving this equation will give us the value of d.
