2.1+Walking+to+the+Yogurt+Shop+10-11

R.B. Math 7D May 28th, 2011 Mr. Goldberg's gym class does an experiment to determine their walking rates. Here are the results from the three students.

Jerome wonders how a persons walking rate could affect the amount of time it takes him or her to walk from school to the frozen yogurt shop.


 * A. If Terry, Jade, and Jerome all leave school together and walk toward the frozen yogurt shop at the rates given in the table, how far apart will they be after 1 minute?**

1(meter)x60(seconds)=60(meters) 2(meters)x60(seconds)=120(meters) 2.5(meters)x60(seconds)=150(meters) __Answer: Terry will go 60 meters, Jade will go 120 meters and Jerome will go 150 meters.__


 * B. If the yogurt shop is 750 meters from school, how long will it take each student to walk there?**

750/1=750 750/60=12 and 30 seconds 750/2=375 375/60=6 and 15 seconds 750/2.5=300 300/60=5 minutes

__Answer: Terry will go 12 minutes and 30 seconds, Jade will go 6 minutes and 15 seconds, Jerome will go 5 minutes.__


 * C. When Jerome arrives a the yogurt shop, how far away will Terry be?**

12.5 -5 --- 7.5

__Terry will be 7 minutes and 30 seconds away from Jerome.__


 * Follow Up**

I used multiplication, division and subtraction.
 * 1. In problem 2.1, what strategies did you use to get your answers?**

Yes, it does because Terry, Jade and Jerome are all going at a constant rate.
 * 2. Does problem 2.1 involve linear relationships? Explain why or why not.**
