Melissa drove 871 miles in 13 hours.

At the same rate, how long would it take her to drive 603 miles?

1 answer

To find out how long it would take Melissa to drive 603 miles at the same rate, we can set up a proportion:

871 miles / 13 hours = 603 miles / x hours

Cross multiplying, we get:

871 * x = 603 * 13

Simplifying the equation, we have:

871x = 7839

To isolate x, we divide both sides of the equation by 871:

x = 7839 / 871 = 9

Therefore, it would take Melissa 9 hours to drive 603 miles at the same rate.
