Lisa is on a bike trip of 762 miles. she has already traveled 510 miles. she has 3 days left in her trip. how many miles does she need to travel each day to complete the trip.

STEP 1:
find the difference between the total miles of the trip (762 miles) and the miles already traveled (510 miles)

= 762 - 510
= 252 miles left of trip

STEP 2:
divide miles left from step 1 by 3 days

= 252 ÷ 3 days
= 84 miles per day

ANSWER: She needs to travel 84 miles each of the 3 days to complete the trip.

Hope this helps! :)
