Answer:
Rate of jogging is 4.6 miles per hour.
Step-by-step explanation:
Rachel jogs 20 feet in 3 seconds and we have to find the rate of jogging in miles per hour.

2x+x+x
-Then you multiply all the Ys
2y * 3y * y
* the Y has a 1 as an exponent by multiplying the Ys the exponents are added making the Y a Y^3
*the numbers are multiplied making it a 6
Together it forms 6y^3
-Ys and Xs cannot be added because they are different values so your answer would be 3x+ 6y^3
