Carrie ran some of the miles and walked some of the miles in a 10-mile race. Each mile she ran took 9 minutes, and each mile she walked took
16 minutes. She finished the race in 120 minutes.
Which system of equations can be used to determine the number of miles Carrie ran, r, and walked, w?
A
r +9= 10
w + 16 = 120
Ð’
r= 10
9r + 16w = 120
c.
r+w=10
9r + 16w = 120
D.
r+w= 10
16r + 9w = 120
