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.
70 minutes
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>

Brainliest is most appreciated :)
The answer would be
y=-1/2x +4
ez, answer choice number 4
y=-1/8x(this is the slope) -4(this is the y intercept
x = 4.363636...
Set up a ratio
6 miles : 55 minutes
x miles : 40 minutes
Cross Multiply
55x = 40*6
55x = 240
55x / 55 = 240 / 55
x = 2 , 3/2
1-1/3 if its 14
1/52 if its 1/4
