Question

Dory biked 11 times as many miles as Carly. Together they biked a total of 156 miles. How many miles did Dory bike?

Answer 1

143 miles

Explanation:

d = dory

c = carly

first, we find the equation from our question:

11c + c = 156

now solve:

11c + c = 156 (add 11c and c)

12c = 156 (divide both sides by 12)

c = 13

since dory bike 11 times that, just multiply 11 and 13 to get the answer:

11 • 13 = 143

dory biked 143 miles

to check:

c +d = 156

13 + 143 = 156

156 = 156 ✅
