Three runners are jogging from North Augusta to Beech Island. Runner 1 runs 14 miles in 3 hours while Runner 2 runs 16 miles in 4 hours. Runner 3 runs 15 miles in 6 hours. What is the average speed of each runner? Then, get the average speed of all the runners together (total distance/total time)

Explanation:

Given that,

Runner 1 runs 14 miles in 3 hours. His average speed is given by :

Runner 2 runs 16 miles in 4 hours. His average speed is given by :

Runner 3 runs 15 miles in 6 hours. His average speed is given by :

Total distance covered by all three runners, D = 14 + 16 +15 = 45 miles  

Total time taken, t = 3 + 4 + 6 = 13 hours

The average speed of all the runners together  is given by :

Hence, this is the required solution.        

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.
