Question

Lee drove a car 2,904.6 kilometers on a recent vacation. The odometer reading on his car was 99,532.4 kilometers when he returned. What was the odometer reading before the trip?

Answer 1

To find the odometer reading before the trip, we just need to subtract the distance that Lee drove in recent vacation form the current odometer reading in his car.
We know for our problem that Lee drove 2,904.6 kilometers and the current odometer reading on his car is 99,532.4 kilometers, so lets perform our operation:
Odometer reading before the trip=$99,532.4km-2,904.6km=96,627.4km$

We can conclude that the odometer reading before the trip was 96,627.4 kilometers.
