Acar averages 2 miles per hour faster than a trolley. if the car travels 190 miles in the same time it takes the trolley to travel 180 miles, then what is the speed of each?

S = speed

 180/s = 190 /s+2

180(s+2) = 190s

180s +360 = 190s

360 = 10s

s = 360/10 = 36

 Trolley is 36 miles per hour

Car = 38 miles per hour

check: trolley: 180/36 = 5 hours, car: 19/38 = 5 hours

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
