Andre and Priya are tracking the number of steps they walk. Andre records records that he can walk 6000 steps in 50 minutes. Priya writes the equation y=118x, where y is the number of steps and x is the number of minutes she walks, to describe her step rate. This week, Andre and Priya each walk for a total of 5 hours. Who walks more steps? How many more?

Answer:

Let's start by calculating the number of steps Andre walked. He recorded that he can walk 6000 steps in 50 minutes, which means that he can walk 6000/50=120 steps per minute. 5 hours = 5*60 = 300 minutes. So Andre has walked 120 * 300 = 36 000 steps.

Priya writes the equation y=118x in which y is the number of steps and x is the number of minutes. As already stated, 5 hours = 300 minutes. So x = 300. We replace x by its value and we get y = 118x = 118*300 = 35400 steps.

36000>35400 so Andre has walked more steps than Priya.

Andre: 6,000 in 50 mins (which means 120 per min)
Prius: 118(50)= 5,900 steps
———————————————-———
Prius : 60(5)= 300 minutes (5hours)
118(300) = 35,400 number of steps
——————————————————
Andre: 120(300) = 36,000 number of steps.
