Question 1095856: A whale is swimming in a straight line at a rate of 34 kilometers per hour. Trailing exactly 2 kilometers behind is a whale-watching tour boat that is traveling 81 kilometers per hour. How long will it be before the tour boat catches up to the whale?
You can put this solution on YOUR website! distance=velocity * time
The boat has to go 2 km at a net closing speed of 81-34 or 47 km/h
2=47 km/h*t h
t=2/47 hours or 120/47 minutes or 2.55 min.
In 2.55 min, the whale will travel 68/47 km; the boat will travel 162/47 km. The latter distance is 2 km more than the first one.
2 minutes and 33 seconds
