How long does it take for a motor boat to sail along the current of 16 km, if the speed of the current is 2 km / h, and the boat’s own speed is 100 m / min.

Initial data: S (distance that the motor boat should sail) = 16 km; Vт (current speed) = 2 km / h; Vl (own boat speed) = 100 m / min.

1) Let’s translate the own speed of the motor boat from m / min to km / h: Vl = 100 m / min = 100 * 60/1000 = 6 km / h.

2) Let’s calculate the speed of the boat downstream:

V = Vt + Vl = 2 + 6 = 8 km / h.

3) Determine the time the boat travels a given distance:

t = S / V = 16/8 = 2 h.

Answer: A motor boat will sail 16 km downstream in 2 hours.
