In 25 minutes, jay can run 10 laps around the track. write an equation to represent the relationship. a) y =. 2 5 x b) y =. 5 2 x c) y = x + 2 5 d) y = x + 5 2

Solution:

The word problem , can be solved by unitary method:

Total time = 25 minutesX Axis

Total Distance traveled= 10 Laps Around the trackY Axis

25 Minutes= 10 Laps

1 Lap  =2.5 Minute

→→y (Lap) = 2.5 x(Minute), where y is time taken, from x=0,1,2,3,and y= Total number of Laps=0,1,2,3,4
