If the sum of upstream and downstream speed is 24 km/hr and the speed of the current is 2 km/hr . Then find the time taken to cover 35 km in downward ?

A

2 hr

B

2.5 hr

C

3 hr

D

3.5 hr

Text Solution

Verified by Experts

The correct Answer is:
B
Let the speed of the boat in still water be x km/hr
ATQ
`x + 2 + x - 2 = 24`
x = 12
Required time `(35)/(14) = 2.5` hr .
