Question

A steamer travels at a speed of 10 km/hr in still water if the same boat
travels upstream with the speed of stream 8 km/hr.

How much time it will take to travel 12 km upstream?

​

Answer 1

90 minutes 1.5 hour is answer

Answer 2

Answer:

Answer:It will take 6 hours to travel 12 km upstream.

Step by step explanation:

Given:

A steamer travels at a speed of 10 km/hr in still water if the same boat travels upstream with the speed of stream 8 km/hr

So,speed of boat $= 10$km/hr

So,speed of stream $= 8$km/hr

We know,

Upstream speed = (Speed of boat - Speed of stream)

For example if speed of boat is x km/hr and speed of stream is y km/hr.

Therefore, upstream speed $= x - y$

Here $x = 10 \:$km/hr

and $y = 8$km/hr.

So, required upstream speed

$= 10-8 = 2$km/hr

→ Time take to cover 12 km in upstream =

$\frac{12}{2} = 6$hours

The required result will be 6 hours.
