Question

Petra jogs 6 miles in 42 minutes. At this rate, how long would it take her to jog 10 miles?

Answer 1

Answer:

70 minutes

Step-by-step explanation:

So if Petra takes 42 min to jog 6 miles, then how long would it take to jog 10 miles? What do we do?

We make a proportion, 6/42 = 10/x

We cross multiply and get an equation of 10*42 = 6*x

We simplify, 6x = 420

And divide 6 by both sides to get x= 70 min

Answer 2

Answer:

It would take Petra 70 minutes to jog 10 miles.

Step-by-step explanation:

There are several ways we can solve this.

As a rate:

42/6=7

One mile takes her 7 minutes.

7*10=70

10 miles takes her 70 minutes.

As a proportion:

6/42=10/x

Cross multiply.

420=6x

x=70

It would take her 70 minutes.
