Question

The current of a stream at 1 kmph. A motor boat goes 35 km upstream and back to the starting point in 12 hours. The speed of the motor boat in still water is ?​

Answer 1

Answer:

hlo

your answer is here !

Step-by-step explanation:

Speed of the stream = 1

Motor boat speed in still water be = x kmph

Down Stream = x + 1 kmph

Up Stream = x - 1 kmph

[35/(x + 1)] + [35/(x - 1)] = 12

x = 6 kmph

Answer 2

Answer:

6 km/hr

Step-by-step explanation:

Let the speed of the boat in still water be x km/hr

• Downstream = x + 1
• Upstream = x - 1

therefore,

[ 35/(x + 1)] + [35/(x -1)] = 12

therefore,

by further solving we get the value of x as 6km/hr
