Ryan is rowing a small boat out to and back from an island 20 miles away at a rate of
x mph. on the way to the island, he has a tailwind of 4 mph that speed him
forward. on the way back, the wind has changed directions and is now a tailwind of 4
mph to speed his return trip home. if the total trip to and from the island takes ryan 5
hours, what is ryan's rowing speed, x?

The speed with which Ryan was rowing was 4 mph

Step-by-step explanation:

With a small boat, Ryan wants to row towards an island and come back at a speed of x mph and the island is 20 miles away from him.  

Therefore, total 20 + 20 = 40 miles he rowed for 5 hours.

On the way to the island, there was a wind of 4 mph in the direction of his motion and on the way back also there was a wind of 4 mph in the direction of his motion.

So, in the total journey, he has a speed of (x + 4) mph.

Therefore,

⇒ x + 4 = 8

⇒ x = 4 mph.

Therefore, the speed with which Ryan was rowing was 4 mph. (Answer)

1/5^2 = 7.56/45

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
