Answer:
The speed on boat in still water is
and the rate of the current is 
Explanation:
Since speed , 
Therefore speed of motor boat while traveling upstream is

and speed of motor boat while traveling downstream is
Let speed of boat in still water be
and rate of current be 
Therefore
----(A)
and
------(B)
Adding equation (A) and (B) we get

=>
------(C)
Substituting the value of
in equation (A) we get

Thus the speed on boat in still water is
and the rate of the current is 
Answer:
The the speed of the car is 26.91 m/s.
Explanation:
Given that,
distance d = 88 m
Kinetic friction = 0.42
We need to calculate the the speed of the car
Using the work-energy principle
work done = change in kinetic energy



Put the value into the formula


Hence, The the speed of the car is 26.91 m/s.
