Question 1154679: At 9:30 car a started its journey at 65 km/h. At 11:00 car B started its journey and travelled at the same road as car a. If car b took 5 hours to catch up with car a find the speed of car b. Found 2 solutions by ikleyn, greenestamps:Answer by ikleyn(52775) (Show Source):
From 9:30 am to 11:00 am, car A covered 65 km/h * 1.5 hours = 97.5 km.
Now let start count the time from the moment of 11:00 am: we have two cars moving.
The distance traveled by car A to the moment of time 11:00 am + 5 hours = 4:00 pm is
97.5 + 5*65 kilometers = 422.5.
So, the car B covered this distance in 5 hours.
Hence, the car B' speed was = 84.5 kilometers. ANSWER
