The average speed is 54 miles per hour.
What is average ?
In plain English, an average is one number chosen to represent a list of numbers. It is often calculated by dividing the total number of numbers in the list by the number of numbers in the list. As an illustration, the sum of the integers 2, 3, 4, 7, and 9 is 5.
The definition of the average is the mean value, which is the ratio of the sum of the values in a given set to the total number of values in the set.
The formula for distance is
Distance = Rate × Time
Total distance = 50 × 3 + 60 × 2 = 270
Total time = 3 + 2 = 5
Using the formula:
[tex]Speed = \frac{Distance}{Time}[/tex]
= 270 / 5
= 54
