Question

A boat goes 48 km downstream in 20 h. it takes 4 h more to cover the same distance against the stream. what is the speed of the boat in still water?2 km/h4.2 km/h2.2 km/h

Answer 1

the answer is 2km/hr as the boat goes against the stream

Answer 2

Answer:

Step-by-step explanation:

Speed downstream =$\frac{48}{20}$ $=2.4$

Speed upstream=$\frac{48}{24}$ = 2 km/hr

Therefore, Speed of boat in still water=$\frac{1}{2} (2.4+2)=\frac{4.4}{2}$

= 2.2km (our final answer)
