Question

Last season 2 running backs on the Steelers football team rushed for a combined total of 1550 yards. One rushed 4 times as many as the others how many yard were rushed by each player.

Answer 1

Answer: the number of yards rushed by one player is 310 while the number of yards rushed by the second player 1240

Step-by-step 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
