Question 1202648
Bob and his brother Jim live 95 miles apart and like to meet and play golf together, the course is 15 miles further for Bob as it is from Jim but Bob averages 10 mph faster than Jim so if they want to meet at the course at 9:00 and Jim leaves at 8:00 what time would Bob need to leave?

Jim's distance = 15 miles
Time taken by Jim = 1 hour   (8.00 to 9.00)

Jim's speed = 15 mph

Bob's speed = 15+10 =25 mph

Bob has to travel 95+15 = 110 miles
t =d/s

110/25 = 4.4 hour

Bob has to  leave 3.4 hours earlier than Jim

0.4 hour = 24 minutes
