To find how many miles Sarah still needs to walk, we subtract the distance she has already walked from the total distance she wants to walk.
Total distance Sarah wants to walk: 5 12 miles = 5 + 12/16 = 5 3/4 miles = 5.75 miles
Distance Sarah has already walked: 2 13 miles = 2 + 13/16 = 2.8125 miles
Miles Sarah still needs to walk = Total distance - Distance already walked
= 5.75 miles - 2.8125 miles
= 2.9375 miles
Therefore, Sarah still needs to walk 2 15/16 miles.
To find out how many miles Sarah still needs to walk, we need to subtract the total miles she has already walked (2 13
miles) from her goal (5 12
miles).
5 12
miles - 2 13
miles = 2 514
miles
Therefore, Sarah still needs to walk 2 514
miles.
