Question

Elena and Lin are training for a race. Elena runs her mile a constant speed of 7.5 miles per hour.

Lin’s times are recorded every minute:
time (minutes) 1 2 3 4 5 6 7 8 9
distance (miles) 0.11 0.21 0.32 0.41 0.53 0.62 0.73 0.85 1
1. Who finished their mile first?
2. This is a graph of Lin’s progress. Draw a graph to represent Elena’s mile on the same axes.
3. For these models, is distance a function of time? Is time a function of distance? Explain how you know.
PLEASE HELP GIVING 200 POINTS NEED DONE ASAP

Answer 1

Elena was there first

Answer 2

Well you aren’t giving 200 points, but I’ll help anyway….
So, 7.5miles per hour, is a mile in 8min flat. That being said, when Lin was about 250m away from the line, 8min were already passed. So, Elena would be there first.
