A car drives 40 miles on local roads at 20 mph, and 180 miles on the highway at 60 mph, what is the average speed of the entire trip?

A. 36 mph

B. 40 mph

C. 44 mph

D. 52 mph

E. 58 mph

Kudos for a correct solution.

Time taken for first \(40\) miles is \frac{40}{20} = \(2\) Hours

Time taken for next \(180\) miles is \frac{180}{50} = \(3\) Hours

So, For travelling 220 miles time taken is 5 Hours.

So, Avg Speed is \(\frac{220}{5} = 44 \ mph\), Answer must be (C)
