Each of two cars, whose average rates are in the ratio of 4:5, travels the distance of 160 miles. If the fast car travels 1 2 an hour less than the slow car, find the average rate of each car.

64mph and 80 mph

Step-by-step explanation:

let be the time and speeds of the two cars in the 160 miles distance.

-Let v represent the speed values:

We are given that the fast car travels 0.5hr less than the slow car, thus:

#We equate the two equations:

#We substitute the value of t in the speed equation to find each cars speed:

The speed of the cars are 64mph and 80 mph

i got 86 for this

hope this !

if you need an explanation just ask
