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

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
