Two trains leave the same station at the same time, but are headed in opposite directions. one train travels at 70 mph and the other train travels at 80 mph. how much times passes until the trains are 600 mi apart?

Time = 4 hours.

Step-by-step explanation:

Since, both the train travels with the speed 70 and 80 mph from the same points in opposite direction.

Thus, we can take speed of train = 70 + 80 = 150 mph

Also, after some time distance between both train is 600 m

Thus, using the formula,

⇒

⇒

⇒ Time = 4 hours.

Thus, After 4 hours both train will 600 m apart.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
