Question

last month, dory rode her bike 11 times as many miles as karly. Together they biked a total of 156 miles. How many miles did dory bike?

Answer 1

The answer is 143 miles.

Step-by-step explanation

The ratio between Dory's miles and Karly's miles is 11:1. This means that we need to divide 156 by 12, which is 13.

Because Dory's miles make up 11/12 of the total miles, we need to take 1/12 (which is 13) from the 156 to get the final answer of 143 miles.
