Question
A boat moves with a downstream speed that is 8 km/hr more
than its upstream speed. If the boat’s speed in still water exceeds the current’s speed by 12 km/hr, calculate the downstream speed of the boat.Solution
ATQ,
Speed of the current = 8 / 2 = 4 km/hr
Speed of the boat in still water = 4 + 12 = 16 km/hr
Downstream speed of the boat = 16 + 4 = 20 km/hr
