Corey and Devante both leave the park at the same time but in opposite directions if Corry travels 30 mph and Devonta travels 22 mph how long until they're 105 miles apart

2 hours 1 minute 9.23 seconds

Step-by-step explanation:

Since they are traveling in opposite directions, their separation speed is the sum of the magnitudes of their speeds: 30 + 22 = 52 mph.

The time is related to speed and distance by ...

time = distance / speed

= (105 mi) / (52 mi/h = 2 1/52 h ≈ 2 h 1 min 9.23 sec

It will take a little over 2 hours before they are 105 miles apart.
