Answer:

7.33333 hours

Step-by-step explanation:

Theo's speed = 55mph

Distance = speed * time

Distance covered after 2 hours

Distance = 55 * 2 = 110 miles (distance already covered by Theo when Dennis left

Dennis speed = 70mph

Let time taken to catch up = x

70x = 110 + 55x

70x - 55x = 110

15x = 110

x = 110 / 15

x = 7.33333 hours
