Question

Four students each ran 100 m in a 400-m relay race. The team’s total time was 49.44 sec. Find the average time of each runner

Answer 1

To get the average time of each runner, you would divide 49.44 by 4. So you should get 12.36 for the average for each runner. Hope this helps!!

Answer 2

The average time of each runner is 12.36 seconds.

We have four students each of whom ran 100 m in a 400-m relay race with team’s total time to complete the race is 49.44 sec.

We have to find the average time of each runner.

What is the formula to find the average of ' n ' numbers?

The formula to find the average of ' n ' numbers is -

$A=\frac{a_{1} +a_{2} +a_{3} \;+.......+\;a_{n} }{n}$

In our question -

$a_{1} +a_{2} +a_{3} \;+.......+\;a_{n}=49.44$

and

n = 4

Since each runner ran the same distance of 100 meters, therefore -

$A=\frac{49.44}{4}$

A = 12.36 seconds

Hence, the average time of each runner is 12.36 seconds.
