perpendicular slope :

m1 * m2 = -1

1/2 * m2 = -1

m2 = -2

y = -2x + b

2 = -4 +b

b = 6

y = -2x + 6

If a bike travels 5 miles in 20 minutes, how long does it take to travel 25 miles?

faust18 [17]

Answer:

100 minutes

Step-by-step explanation:

To solve this, we can make a proportion.

The bike travels 5 miles in 20 minutes, and 25 miles in x minutes

5/20=25/x

Cross multiply

5*x=20*25

5x=500

Divide both sides by 5. This will cancel out the 5, and leave x by itself.

5x/5=500/5

x=100

There are 60 minutes in 1 hour. If we subtract 60 from 100,

100-60=40

So, this is also equivalent to 1 hour and 40 minutes.

It takes 100 minutes, or 1 hour and 40 minutes, to travel 25 miles.
