Help me with this basic math word problem:?

Question

Two runners finished a race in 80 seconds, another runner finished the race in 72 seconds, and the final runner finished in 68 seconds. The average of these times is?? What do I add and divide? Is that how I get an average?? Thanks a lot.

Answer 1

Take all three numbers add them all together. Divide the sum by how many numbers you have. That should then be your average.

Answer 2

add all divide by four that's the average i.e.

80 + 80 +72 + 68 = 300 / 4 = 75 average

Answer 3

to find the average you add up the numbers , then divide it by the number of numbers. So do this.

80+80+72+68 = ? divided by 4. People who just give you the answer aren't helping , how is she going to learn?

Answer 4

yup add 80+72+68and80 because of @nd runner

then divide by 4= 300/4= 75

so ur answer is 75 seconds

Answer 5

To get an average you add all the amounts and divide the total by the number of values. So:

80 + 80 + 72 + 68 = 300

There are four values, so:

300 / 4 = 75 seconds

Don't forget the units in your answer; here the units are seconds.
