Ruiz average speed, in miles per hour, for two days is 55 miles per hour

Solution:

The average speed is given as:

$Average\ Speed = \frac{ \text{ total distance traveled }}{ \text{ total time taken }}$

Mr. Ruiz drove 305 miles in 5 hours on saturday and 190 miles in 4 hours on Sunday

Total distance traveled = 305 + 190 = 495 miles

Total time taken = 5 + 4 = 9 hours

Therefore,

$Average\ Speed = \frac{ 495 }{ 9 } = 55$

Thus, his average speed, in miles per hour, for two days is 55 miles per hour
