Two cars are 180 mi apart and travel toward each other along the same road. They meet in 4 hr. One car travels 5 mph slower than the other car. What is the average speed of each car?

The speed of the slower car = 20 mph

The speed of the faster car = 25 mph

Step-by-step explanation:

Let the speed of the slower car be s - 5

Let the speed of the other car be s

Two cars are 180 mi apart and travel toward each other along the same road. They meet in 4 hr.

Hence, the total speed = Distance/Time

= 180 miles/4hr

= 45 miles/hr or 45mph

Therefore:

s + s - 5 = 45 mph

2s - 5 = 45 mph

2s = 45 + 5

2s = 50

s = 50/2

s = 25 mph

The speed of the other car = s = 25mph

The speed of the slower car be s - 5

s - 5

= 25 - 5 = 20mph

Therefore,

The speed of the slower car = 20 mph

The speed of the faster car = 25 mph

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

168

step-by-step explanation:

i am pretty sure that the answer is 168
