Answer:
y = 45x miles
Step-by-step explanation:
Speed is the rate of change of distance with time. Mathematically,
speed = distance/time
Given that Darla travels at a constant speed of 45 miles per hour and for y miles, it takes her x hours then
45 = y/x 
multiply both sides by x
45x = y
then the number of miles (y) Darla can drive in x hours
y = 45x (in miles)

Answer:
part 1= "72=(2w)+(w-15)"
part 2= "29"
I'm not sure if they want "w = abc"
I used that equation to solve part 2
