Last season two running backs on the steelers football team rushed or a combined total of 1550 yards. one rushed 9 times as many yards as the other. how many yards were rushed by each player?

First we define variables:
 x = distance traveled by player A
 y = distance traveled by player B
 We have the following system of equations:
 x + y = 1550
 x = 9y
 Solving the system we have:
 x = 1395
 y = 155
 
 x = 1395 yards (player A)
 y = 155 yards (player B)

If gravity is one third on mars then weight also one third on mars
