Answer:
11 pm
Step-by-step explanation:
From 1 pm to 4pm, its been 3 hours.
First car traveled [tex]35*3=105[/tex] miles before the 2nd car started. Hence, second car is 105 miles behind.
Second car's speed is [tex]50-35=15[/tex] mph more than first car, so he catches up 15 miles in 1 hour.
Second car needs to catch-up 105 miles @ catching-up rate of 15 miles every hour.
So, its gonna take 7 hours ([tex]\frac{105}{15}=7[/tex] for the 2nd car to catchup.
7 hours from 4pm is at 11pm (they will meet)
