Answer: the number of yards rushed by one player is 310 while the number of yards rushed by the second player 1240
Explanation:
Let x represent the number of yards rushed by one player.
Let y represent the number of yards rushed by the second(faster) player.
Last season 2 running backs on the Steelers football team rushed for a combined total of 1550 yards. This means that
x + y = 1550 - - - - - -- - -- - - - - - 1
One rushed 4 times as many as the other. This means that
y = 4x
Substituting y = 4x into equation 1, it becomes
x + 4x = 1550
5x = 1550
x = 1550/5
x = 310
y = 4x = 4 × 310
y = 1240
