Question

Mrs. Travis rode her bike 17.8 miles the first week, 21.5 miles the second week, and 13.4 miles the third week. The rest of her mileage was in the final week of the month. Her total mileage for the month was 62.9 miles.

Answer 1

She rode her bike 10.2 mile the final week.

You simply just add all of the numbers together & subtract from 62.9 then get 10.2.

Hopefully this helps! :-)
