A motor boat travels 48 miles down a river in two hours but takes twice as long to make the return trip upstreamFind the speed of the boat in still water and the rate of the current

speed of the current is 6 miles per hour.

Speed of the boat in still water is 18 miles per hour

Step-by-step explanation:

-Speed is defined as displacement over time.

-Let a be the speed in still water and b be speed of  the current of the river.

#The speed downstream is equated as:

#The speed upstream in 4hrs is equated as:

we make a the subject of the formula in i and substitute in ii:

Hence, speed of the current is 6 miles per hour and

Speed of the boat in still water is 18 miles per hour
