1 answer:
Answer:
11.00 pm
Step-by-step explanation:
Given that at 11:00 AM a bus left San Jose travelling to Los Angeles at 48 mph. Hence in 4 hours it would have travelled
48x4 = 192 miles
When the bus travelled 192 miles a motorcyclist started in the same direction with speed 72 mph
Difference in speed per hour = 72-48 = 24 mph
TO cover the distance of 72 miles, time taken for the motorcycist would be
192/24 = 8 hours
In 8 hours or at 11.00 p.m. motorcycle will catch upto the bus,
