Ineed to graduate. 20 ! two trains leave the station at the same time, one heading east and the other west. the eastbound train travels at 60 miles per hour. the westbound train travels at 80 miles per hour. how long will it take for the two trains to be 252 miles apart? do not do any rounding.

Let t be the time taken by trains

The eastbound train travels at 60 miles per hour.

we know Distance = speed * time

Speed is 60 miles per hour

So distance traveled by eastbound train = 60 t

The westbound train travels at 80 miles per hour.

Speed is 80 miles per hour

So distance traveled by westbound train= 80 t

Two trains are 252 miles part

Distance covered by eastbound train + distance covered by westbound train= 252

60t + 80 t = 252

140t = 252

Divide both sides by 140

So t= 1.8

It will take 1.8 hours for the two trains to be 252 miles apart

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
