Abus and a car leave from the same city traveling in opposite directions. the bus leaves 2 hours before the car does. the bus travels at a steady speed of 50 mph while the car travels at 70 mph. after how many hours will the bus and car be 800 miles apart?
if h represents the number of hours the bus travels, then which of the following expressions represents the number of miles the car travels?
70(h + 2)
70(h - 2)
70h

After 7.8 hours (7 hours 48 min.) will the bus and car be 800 miles apart

70(h-2) expression represents the number of miles the car travels.

Step-by-step explanation:

If h represents the number of hours the bus travels.

In the question it is said that the bus leaves 2 hours before the car does

Therefore car travels (Time) = ( h-2 )

car's speed = 70 mph,

Distance = speed × time = 70(h-2)

70(h - 2) expression represents the number of miles the car travels.

If we want to find the number of hours will the bus and car be 800 miles apart we can solve it as :

50h + 70(h-2) = 800

50h + 70h - 140 = 800

120h = 800 + 140

120h = 940

h = 940 ÷ 120 = 7.833... = 7.8 hours (7 hours and 48 min.)

Ans. After the bus left the city, after 7.8 hours the car and the bus will be 800 miles apart.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
