Step-by-step explanation:
Answer:
15 miles.
Step-by-step explanation:
3/8 x 40 = 120/8
now divide,
120/8 = 15
Let
be the weight of i-th player.
1. If the mean weight of 4 backfield members on the football team is 221 lb, then
![\dfrac{x_1+x_2+x_3+x_4}{4}=221\ lb.](https://tex.z-dn.net/?f=%5Cdfrac%7Bx_1%2Bx_2%2Bx_3%2Bx_4%7D%7B4%7D%3D221%5C%20lb.)
2. If the mean weight of the 7 other players is 202 lb, then
![\dfrac{x_5+x_6+x_7+x_8+x_9+x_{10}+x_{11}}{7}=202\ lb.](https://tex.z-dn.net/?f=%5Cdfrac%7Bx_5%2Bx_6%2Bx_7%2Bx_8%2Bx_9%2Bx_%7B10%7D%2Bx_%7B11%7D%7D%7B7%7D%3D202%5C%20lb.)
3. From the previous statements you have that
![x_1+x_2+x_3+x_4=221\cdot 4=884 \lb,\\ \\x_5+x_6+x_7+x_8+x_9+x_{10}+x_{11}=202\cdot 7=1414\ lb.](https://tex.z-dn.net/?f=x_1%2Bx_2%2Bx_3%2Bx_4%3D221%5Ccdot%204%3D884%20%5Clb%2C%5C%5C%20%5C%5Cx_5%2Bx_6%2Bx_7%2Bx_8%2Bx_9%2Bx_%7B10%7D%2Bx_%7B11%7D%3D202%5Ccdot%207%3D1414%5C%20lb.)
Add these two equalities and then divide by 11:
![x_1+x_2+x_3+x_4+x_5+x_6+x_7+x_8+x_9+x_{10}+x_{11}=884+1414=2298\ lb,\\ \\\dfrac{x_1+x_2+x_3+x_4+x_5+x_6+x_7+x_8+x_9+x_{10}+x_{11}}{11}=\dfrac{2298}{11}=208\dfrac{10}{11}\ lb.](https://tex.z-dn.net/?f=x_1%2Bx_2%2Bx_3%2Bx_4%2Bx_5%2Bx_6%2Bx_7%2Bx_8%2Bx_9%2Bx_%7B10%7D%2Bx_%7B11%7D%3D884%2B1414%3D2298%5C%20lb%2C%5C%5C%20%5C%5C%5Cdfrac%7Bx_1%2Bx_2%2Bx_3%2Bx_4%2Bx_5%2Bx_6%2Bx_7%2Bx_8%2Bx_9%2Bx_%7B10%7D%2Bx_%7B11%7D%7D%7B11%7D%3D%5Cdfrac%7B2298%7D%7B11%7D%3D208%5Cdfrac%7B10%7D%7B11%7D%5C%20lb.)
Answer: the mean weight of the 11-person team is ![208\dfrac{10}{11}\ lb.](https://tex.z-dn.net/?f=208%5Cdfrac%7B10%7D%7B11%7D%5C%20lb.)
