Let X be the number of hours
Brady drives 60 mph for X number of hours, which is written as 60x.
Mary drives 45 mph for x number of hours, which is written as 45x.
The equation to solve for the number of hours is:
60x + 45x = 1365

x = 1365 / 105
x = 13 hours.

Answer:
10,11,12
Step-by-step explanation:
X+x+1+x+2
X+2(x+1)=x+2 + 20
X +2x+2 = x+22
3x+2 = x+22
2x +2 = 22
2x = 20
X = 10
Numbers are 10,11,12
Double checking 10+2*11 = 32
12+20 = 32
So it works
