Answer:
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.
