Question

A boat with speed of 1.20 km/h relative to the water is heading for a dock 2.29km downstream. If the river speed is 0.384 km/h, how many minutes will it take to reach the dock?

​

Answer 1

87min

Step-by-step explanation:

v_boat = v_boat/water + v_water

v_boat = 1,2 + 0,384 = 1,584

s = vt

t = s/v = 2,29/1,584 * 60 min = 87min
