Question

On her bike, Katie can ride an average of 6 miles per hour. If she rides for one hour and thirty minutes, how far did she go? (Use proportions)

Answer 1

9 mph

Explanation:

proportion:

6/1 = x/1.5

use cross multiplication

1(x) = 6(1.5)

x = 9

Answer 2

Katie went a distance of 9 miles.

Explanation:

To find out how far Katie went when riding her bike for one hour and thirty minutes at an average speed of 6 miles per hour, you can use proportions.

First, you need to convert one hour and thirty minutes into hours. Since there are 60 minutes in an hour, one hour and thirty minutes is equivalent to:

1 hour + (30 minutes / 60 minutes) = 1.5 hours

Now that you know she rode for 1.5 hours at a speed of 6 miles per hour, you can set up a proportion to find the distance (d):

(1.5 hours / 1 hour) = (d miles / 6 miles per hour)

Now, cross-multiply and solve for d:

1.5 hours * 6 miles per hour = d miles

9 miles = d miles
