CPM Homework Help : MC2 Problem 7-38

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. List the runners from slowest to fastest.

Runner A: slope $=\frac { 2 } { 6 }$

Runner B: slope $=\frac { 3 } { 7 }$

Runner C: slope $=\frac { 5 } { 12 }$

Runner D: slope $=\frac { 4 } { 10 }$

Hint:

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.

Help:

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

More Help:

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.
