Exercising Distance (miles) Time (minutes) Gia 2 30 Harris 5 50 Ian 3 40 Jackson 4 80 Which list ranks the students from fastest walker to slowest walker? Jackson, Gia, Ian, Harris Harris, Jackson, Ian, Gia Harris, Ian, Gia, Jackson Jackson, Harris, Ian, Gia

Answer 1

Answer:

Harris, Ian, Gia, Jackson.

Step-by-step explanation:

                   Exercising Distance (miles)       Time (minutes)

Gia              2                                                  30

Harris          5                                                  50

Ian               3                                                  40

Jackson      4                                                  80

The easiest thing to do here would be to calculate how many miles each person can walk in 1 minute.

Gia takes 30 minutes to walk 2 miles. That means that her speed is 2/30, or 1/15, or 0.0667 miles per minute.

Harris takes 50 minutes to walk 5 miles. That means his speed is 5/50, or 1/10, or 0.1 miles per minute.

Ian takes 40 minutes to walk 3 miles. That means his speed is 3/40, or 0.075 miles per minute.

Jackson takes 80 minutes to walk 4 miles. His speed is 4/80, or 1/20, or 0.05 miles per minute.

From here, we can see that Jackson can walk the least miles per minute, since his rate is just 0.05 miles per minute. Next is Gia, who walks 0.0667 miles per minute. Then Ian, who walks 0.075 miles per minute, and finally Harris, who walks 0.1 miles per minute.

So, the order from fastest to slowest is Harris, Ian, Gia, Jackson.

Hope this helps!
