h

Explanation:

We're asked to find the time

t

it takes a boat to travel

68

km

.

We know:

speed of boat with respect to earth:

13

km/h

speed of stream with respect to earth:

4

km/h

We're given that the boat travels downstream, i.e. with the current, so the new speed of the boat is

13

km/h

+

4

km/h

=

17

km/h

The time to travel

68

km

with this speed is thus

t

=

68

km

17

km

h

=

4h

hope it helps. pls maek as brainliest, and a thanks plss
