A car travels 200 miles in the same time that a train travels 300 miles. The speed of the train is 20 miles per hour more than t

scZoUnD [109]

The equation is
time= distance/rate
and the train is going 300 miles
the car is going 200 miles
the train goes 20 miles faster than the car
fitting the numbers into the equation
200/r=300/(r+20)
cross multiply
200/r = 300/(r+20)
200(r+20) = 300r
distributive property
4000+200r=300r
subtract 200r from both sides to add like terms
4000=100r
divide 100 from each side to get r by itself
40 = rate of car
60 = rate of train

656 + x = 900
x = 900 - 656
x= 244
