Answer:

12:05 pm (Please mark me as the brainiest)

Step-by-step explanation:

Number of hours = w, from 11:00 am, when Jimmy would catch up with John. The time that Jimmy will have to drive to catch up with John is z - 1/4 as he started a quarter of an hour late. When Jimmy would catch up with John, they would have traveled the same distance. Hence

50 w = 65 (w - 1/4)

Find time (t):

50w = 65w - 65/4

w = 65/60

= 1.083

= 1 hr 5 min

Jim will catch up with John at

11:00 am + 1 hour 5 minutes = 12:05 pm
