Question

Jennifer can run 5 miles in 45 minutes. At that rate, appropriately how far could she run In 120 minutes

Answer 1

If Jennifer can run 5 miles in 45 minutes, then

45/5 = 9

This means that Jennifer runs 1 mile in 9 minutes

So, in 120

120/9 =

13.33 or

13 1/3 miles in 120 minutes

Answer 2

Start by setting up the ratios:

5 miles. X miles

_____ = ______.

45 min. 120 min

Simplify the 5 to 1. by dividing both 5 and 45 by 5.

---- __

45. 9

Now you have a ratio of 1/9 = x/120

Divide 9 and 120 by 3.

You get 1 = x

__ ___. if you cross multiply you get 3x=40

3 40

X= 40/3. =. 13.3 miles.

You can also just cross multiply 5 x120 = 45x

600=45x

X= 600/45 = 13.33 miles

Answer 3

If she runs 5 miles in 45 minutes:

45 divided by 5 = 9 minutes per mile

120 divided by 9 minutes = 13.33 miles

Answer 4

Since it looks like she can run a mile in 9 minutes and 120 minutes, one would divide 120 by 9 to get approximately 13.3 miles, given that she can keep up the pace.

Answer 5

x/120=5/45=1/9

x/40=1/3

x=40/3=

13 1/3 miles in 120 minutes

5 miles in 3/4 of an hour

that's 5x4/3 = 20/3 = 6 2/3 mph

5 mph is an average walk

120 minutes = 2 hours

in 2 hours she can run 2x6 2/3 = 13 1/3 miles

assuming she keeps up the same pace
