Question

1) Noah is running a portion of a marathon at a constant speed of 6 miles per hour. Complete the table to predict how long it would take him to run different distances at that speed, and how far he would run in different time intervals. time in hours miles traveled at 6 miles per hour 1 1 2 1 1 3 1 1- 2 1 4 2

Answer 1

Okay, here we have this:

According with the provided info we obtain the following function:

y=6x, where y represents the miles traveled and x the time in hours. Now let's replace with the values in the table to complete it:

When x=1:

y=6x

y=6*1

y=6

When x=1/2:

y=6x

y=6*(1/2)

y=3

When x=1 1/3=4/3:

y=6x

y=6(4/3)

y=8

When y=1/2:

y=6x

1/2=6x

x=1/12

When y=9:

y=6x

9=6x

9/6=x

x=3/2

When y=4 1/2=9/2:

y=6x

9/2=6x

x=9/12

x=3/4
