A man drives to town 30 miles away at a speed of 45mph and arrives in 40 mins On his return he takes 60 mins What is his average speed for the total trip?

To find the average speed for the total trip, first calculate the total distance: 30 miles each way totals 60 miles. The total time taken is 40 minutes (0.67 hours) for the trip to town and 60 minutes (1 hour) for the return, totaling 1.67 hours. The average speed is then calculated by dividing the total distance by the total time: 60 miles / 1.67 hours ≈ 35.9 mph.
