The speed of a car is km in the first hour and km in the second hour. What is the average speed of the car?

Calculated Answer

66

Step by Step Solution

In order to solve problem, you must evaluate (n₀ + n₁) / 2.

n₀ =	90
n₁ =	42

(n₀ + n₁) / 2
Evaluate n₀ + n₁ = 132
132 / 2
Evaluate 132 / 2 = 66
66
The answer to the problem and the result of (n₀ + n₁) / 2 is 66
