Question

On a trip to the African Savannah a biologist studies the hunting methods of Cheetahs. Using a radar gun, he measures the speed of Cheetahs while they are chasing prey. He records the following data for their top speeds: 75 mph, 74 mph, 77 mph, 79 mph, 80 mph, 76 mph. What is the average top speed of the Cheetahs?

Answer 1

Answer:

$76.83$ mph

Explanation:

The average of a group of number is equal to the sum of all the numbers divided by the total number of entries.

Thus, mathematically average is equal to

$\frac{A_{1} + A_{2} + A_{3} + A_{4} .....+ A_{n} }{n}$

Substituting, the given speed data in above equation, we get -

$=\frac{75+ 74+77+79+80+76}{6}\\= \frac{461}{6} \\= 76.83$ mph

Hence, the average speed  of Cheetahs is $76.83$ mph

Answer 2

The average top speed of the Cheetahs is 76.83333333333.... miles per hour.

You must find the arithmetical mean, which is solved by adding all the given numbers, and then dividing that by the number of numbers you added(it sounds weird but it is pretty simple).

75 + 74 + 77 + 79 + 80 + 76 = 461

461/6 =

76.83333333333....
