The average speed of his trip is = 12 mile/ hour
The total distance covered by the driver = 240 miles
The rate at which he traveled = 12 miles per hour
Therefore, the time he used to cover his distance
= 240/12
= 20 hrs

= 240/ 20
= 12 miles/ hour
Therefore, the average speed of his trip is = 12 mile/ hour
