Question

A police officer recorded the speeds of the first six cars whose drivers he ticketed for speeding today.

Car Speed
(miles per hour)
1 67
2 74
3 85
4 80
5 74
6 82

What is the mean of the cars' speeds?

Answer 1

The mean is 77.

Explanation:

Step one: add all the numbers

Step two: Divide the sum by the number of values you added

(example: 1,5,8,12,13. You would add them together, since we have 5 numbers, we will divide the sum by 5, then we have the mean)

462 divided by 6 is 77

Hope this helps!
