Let the speed of Ben be x mph. Therefore, the speed of Alan is x - 0.6 mph. Their combined speed is 2x - 0.6 mph. This is equal to 11.4 miles divided by 3 hours. i.e.3.8 mph.

2x - 0.6 = 3.8,

2x = 3.8 + 0.6 = 4.4

x = 4.4/2 = 2.2

Therefore, the speed of Ben is 2.2 mph and the speed of Alan is 1.6 mph.
