So far, the Rabun family has traveled 30 miles in 1/2 hour. If it is currently 3:00 P. M and their destination is 75 miles away from them, at what time will the Rabun family reach their destination? Explain how you solved the problem.

Rabun family travel = 30 miles in 1/2 hours or in 30 minutes.

Therefore, in 1 hour Rabun family will travel = 2 * 30 = 60 miles.

Total number of miles they need to travel now = 75 miles.

75 miles = 60 miles + 15 miles.

60 miles traveled in 1 hour.

15 miles traveled in 1/4 hours or 15 minutes.

Total time taken to travel 75 miles = 1 hour 15 minutes.

Current time is 3:00 P. M.

After 1 hour and 15 minutes the time will be 4:15 P. M.

Therefore, Rabun family will reach their destination at 4:15 P. M.
