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

60

Step by Step Solution

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

n₀ =	90
n₁ =	30

(n₀ + n₁) / 2
Evaluate n₀ + n₁ = 120
120 / 2
Evaluate 120 / 2 = 60
60
The answer to the problem and the result of (n₀ + n₁) / 2 is 60
