A boat takes 3 hours to reach a destination 48 km away when it goes downstream and takes 4 hours
for the return journey. What is the speed of the boat? What is the speed of the water current
(Assume that both the speeds of the boat and the water current are constants.)

speed of the boat is 8.52 mphs,   the current of the water is 6.2 mphs

Step-by-step explanation:  96 km divided by 7. to find the speed of the boat change km to mph. 8.52 mph boat speed.  

For the current divide 48 km by 3 and the same by, then the the results and then divide by 2.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

it would take 7/10 of an hour too fill the pool.
