Answer:
4/5
Step-by-step explanation:
formula for slope is (y2-y1)/(x2-x1)
Butter pecan: 25
Vanilla: 35
Chocolate: 50
The dotted line between 20 and 30 (butter pecan) will be nothing more than anything including 5. In this case, it is 25 counting up to 30.
The solid lines directly leading to a number will be that number, for instance, chocolate is 50.
The length of the race is 5 kilometers.
5 kilometers equals 5000 meters.
Since Lana's avarege step length is about 0.5 meters, we need to divide 5000 by 0.5

Hence, Lana needs to take about
10000 steps.
