A boat rescued people drowning in a river during a flood,
with maximum of 5 people at a time 7 people were holding
a rock in middle of water flow. The boat arrives and
picks 5 of them and left 2 people holding the rock. When
the boat began to travel upstream, 2 people holding the
rock, left hold of it and start flowing with the water flow.
The boat travels 2 km upstream, left the 5 people, turned
about and caught with the 2 people drowning. How long
will it take the boat to reach those 2 people?
Take, speed of boat w.r.t. to still water = 10 m/s
Speed of water flow = 2 m/s
