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 <u>x= 70 min</u>
