Question 1
A boat travels at 16 km/h in still water. The stream flows at 3 km/h. How long will it take to go 72 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 16 + 3 = 19 km/h
2. Time = Distance / Speed = 72 / 19 = 3.8 hours
1. Downstream speed = Boat speed + Stream speed = 16 + 3 = 19 km/h
2. Time = Distance / Speed = 72 / 19 = 3.8 hours
