A motor travels 10 mph in still water. The boat takes 4 hours longer to travel 48 miles going upstream than it does to travel 24 miles going downstream. Find the rate of the current.

The rate of the current is 2 mph.

Step-by-step explanation:

When the boat travels upstream we have:

Where:

: is the total speed

: is the speed of the boat = 10 mph

: is the speed of the current

x: is the distance

t: is the time

And when the boat travel downstream we have:

Since the boat takes 4 hours longer to travel 48 miles going upstream than it does to travel 24 miles going downstream we have:

  (1)

  (2)

By adding equation (1) with (2):

By solving the above equation for t we have:

t = 2 h      

Now, by entering "t" into equation (2) we have:

Therefore, the rate of the current is 2 mph.

I hope it helps you!  

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
