Delivery Van	Electricity Usage (kWh)
Van A	180
Van B	200
Van C	300
Van D	250
Van E	150

Calculate the average electricity usage (in kWh) for the 5 delivery vans listed above.

The correct answer is 216.

To calculate the average electricity usage for the delivery vans, we use the formula for the arithmetic mean:

$\text{Average}=\frac{\text{Sum of all values}}{\text{Total number of values}}$

Step 1: Find the total electricity usage by adding the usage values for all 5 delivery vans provided in the table:

$\text{Total Usage}=180+200+300+250+150$

$\text{Total Usage}=1080\text{kWh}$

Step 2: Divide the total electricity usage by the total number of delivery vans (5):

$\text{Average Electricity Usage}=\frac{1080}{5}$

$\text{Average Electricity Usage}=216\text{kWh}$

Therefore, the average electricity usage for the 5 delivery vans is 216 kWh.
