Answer:
They would meet each other at
PM.
Step-by-step explanation:
- Erik took a trip to see his friend Mike who lives 308 miles away.

As Erik left his house at 10 AM driving at 70 mph and in 2 hours, his friend Mike left his place driving towards Erik at an average speed of 50 mph. It means
Erik left his place at 12:00 PM noon.

50/50
With a two-sided coin, the probability of it landing on heads or tails will always be 50.
4 over 12 times 8 over 20
= 4/12 * 8/20 ....( 4/12 = 1/3; 8/20 = 2/5)
=1/3 * 2/5
=2/15
