Question

Hari can row at a speed of 4km/hr in still water. How long will he take to row upstream 6 kms and then
downstream 6 kms in a current with velocity/speed 2 km/hr?

Answer 1

Answer:

4hour

Step-by-step explanation:

Down stream speed 4+2 =6km/hr

For 6 km down stream hari take 6/6=1hr

Up stream speed 4-2=2km/hr

For 6km up stream hari take 6/2=3 hr

So total time 3hr+1hr=4hr
