Question

A man can row 30 km upstream in 6 hours. If the speed of the man in still water is 6 km/hr, how much (in km) can he row downstream in 10 hours?​

Answer 1

Answer:

speed of man when going in upstream = 30/6 = 5/1

= 5km/hr

speed of man in still water = 6km/hr

speed of man when he would go downstream= 7km/hr

he will go downstream in speed of 7km/hr so the distance covered will be 7×10 = 70 km

Therefore, he can go 70km downstream in 10 hours.
