distance east=55km
distance west=338-55= you do it.
avg speed going west= distance/time
= (338-55)/(2.6-1.6)
Your teacher is too easy.
A car drives 55 km east in a time of 1.6 hours and then drives west some distance. However, the total distance traveled for the entire trip is 338 km and the total time taken for the entire trip is 2.6 hours. What is the average speed of the second part of the trip (when heading west) in km/hr?
