7-50.

Lydia drew a graph of four athletes in the final part of the triathlon, the 10 km run. She found the slope of each runner’s line. Her results are listed below. Homework Help ✎

Runner A: slope =

Runner B: slope =

Runner C: slope =

Runner D: slope =

List the runners from slowest to fastest.

The fastest athlete will have the greatest slope, because that means that they were able to run a greater distance in a given amount of time.

One way to see which runner had the greatest slope is to convert each fraction into a decimal.

The decimal approximation for Runner A is 0.33 and for Runner B it is 0.43.

Find the decimal values for the other two runners, then arrange them from least to greatest.
