Acar left ottawa at 1 p. m. going at 35 mph. a second car left the city at 4 p. m. going in the same direction at 50 mph. at what time will the second car catch up with the first?

11 pm

Step-by-step explanation:

From 1 pm to 4pm, its been 3 hours.

First car traveled miles before the 2nd car started. Hence, second car is 105 miles behind.

Second car's speed is 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 ( for the 2nd car to catchup.

7 hours from 4pm is at 11pm (they will meet)
