Please help ASAP!!!!!!! This is due TOMORROW!!!!

1. Noah is running a proportion of a marathon at a constant speed of six 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.

Given the constant rate of 6 miles per hour, we can simply multiply the time by the rate to get distance. Remember, 6mph means the runner travels 6 miles every hour. We can formulate an equation to represent this data:

d=r•t

Distance equals rate multiplied by time.

d=6•1

d=6

So, your answer for the first column is 6 miles as our distance equation shows.

For column 2:

d=6•1/2

d=3

3 miles is the distance for the second column

For the 3rd column:

First, let’s convert 1 and 1/3 to a decimal for simpler arithmetic:

1 and 1/3 is equivalent to 1.333 since the runner ran one whole miles and 1/3 of the next.

d=6•1.333

d=7.998

So, the answer to column 3 is 7.998 miles or 8 miles when rounded.

For the 4th column:

We are now given the distance and need to find the time, so we input the values in for the variables:

1.5=6t

We know the runner traveled 1.5 miles at 6 miles per hour. We solve for t now:

1.5/6=t

t=.25 or a quarter of an hour. Remember, a quarter of an hour is 15/60 minutes. So, 15/60 is the answer for column 4.

For column 5:

9=6t

9/6=t

1.5=t

So, 1.5 hours is your answer for column 5.

For column 6:

4.5=6t

4.5/6=t

.75=t

.75 is 75% and 75% of an hour is 45/60 minutes. So, 45/60 minutes is your answer for column 6.

Hope this helps!
