Question

The velocity of a boat with respect to the shore is 2 meters/second. The velocity of the water with respect to the shore is 1 meter/second. What is the distance traveled by boat after 3 minutes if the boat is traveling in the opposite direction of the water? (Hint: Find the velocity of the boat relative to the water and then use the equation distance = speed × time)

Answer 1

180, since the water counteracts 1/2 of the movement of the boat. 3 minutes is 180 seconds, so, you get 180.

Answer 2

Answer;

540 meters

Explanation;

The velocity of the boat relative to the water;

2 m/s + 1 m/s = 3m/s  

Time is 3 minutes;

but 1 minute =60 seconds

Therefore; time is = 3 ×60 = 180 seconds

Distance = velocity × time

                 = 3 × 180 = 540 m

          = 540 meters
