Mario travels for 3 hours at an average speed of 41 mph, then 4 hours at an average speed of 48 mpph. What is his average speed for the whole trip?
========================================================================
The total distance traveled during the trip = 41 mph * 3 h + 48 mph * 4 h = 315 mi
The total travel time was 3 h + 4 h = 7 h
Therefore the average speed was 315 mi/7 h = 45 mph
