Answer:
Step-by-step explanation:
Given that cesar left the college traveling 12 mph. Then, 4 hours later, Gabriel left traveling the same direction at 24 mph.
Before Gabriel started Cesar would have travelled for 4 hours
So distance travelled by Cesar in 4 hours
Thus Cesar is ahead of Gabriel by 48 miles
Difference of speed
So to catch Cesar time required = 48/difference in speed
= 4 hours
It will take 4 hours.
