Question

On a long distance bike trip Annike started at 7 a.m and her average speed was 11 miles per hour and Celia travels 14 miles per hour.

Write an equation
When will the two have completed the same number of miles

Answer 1

Annike's bike trip started at 7:00, if she and Celia both start at the same time you would multiply Annike's average speed by Celia's average speed to find where they would have completed the same number of miles

equation: 11×14=154 14×11=154

Explanation:

counting by 11:

11 22 33 44 55 66 77 88 99 110 121 132 143 154

11 × 14 = 154

counting by 14:

14 28 42 56 70 84 98 112 126 140 154

14 × 11 = 154
