Last month, Dory biked 11 times as many miles as Karly. Together they biked a total of 156 miles. How many miles did Dory bike last month?
Answer provided by our tutors
let
d = the miles that Dory biked
k = the miles that Karly biked
Dory biked 11 times as many miles as Karly
d = 11k
Together they biked a total of 156 miles
d + k = 156
by solving the system of equations
d = 11k
d + k = 156
we find
d = 143 miles
