Question

A boat travels 10 km with the ow in 2 hours and 30 minutes. Against the ow, the boat takes twice the time to travel
half the distance. Find the ratio of speed of boat in still water to that of the current?​

Answer 1

Answer:

1:2.30

Step-by-step explanation:

10km is travelled by the boat in 2hrs 30mins.

Hence,speed of boat=2hrs 30mins/10km

=(2.30/10)km/hr

=2.3km/hr

speed of boat against the current={2(2.3)€}km/hr

=5km/hr

Therefore,the ratio=2.3km/hr : 5km/hr

=1 : 2.3(ans)
