Question

Nikki is driving a motorboat across a river that flows at 5 m/s. The motorboat has a speed of 12 m/s in still
water. She heads out from one bank in a direction perpendicular to the current. How far does she travel in 3
minutes?

Answer 1

3 min = 180 seconds

downstream = 5 * 180
across = 12 * 180

hypotenuse = sqrt (across^2 + downstream^2)
