Answer:
1 hour 42 minutes
Step-by-step explanation:
Given: Speed of 1st trucker= 62 mph
Speed of 2nd trucker= 66 mph
Total distance need to cover to be in contact is 270 miles
1st trucker start 1 hour ahead of 2nd trucker
Lets assume 2nd trucker take `x` hours to be in contact and 1st trucker take `(x+1)` hours.
We know, distance= 
1st trucker, distance
∴ 
2nd trucker, distance
∴
Now, putting the values in an equation.

⇒ 
Opening the parenthesis to solve and subtracting both side by 62
⇒ 
∴ x=
= 1 hour 42 minutes
∴ It will take 1 hour 42 minutes to be able contact each other after first trucker leaves.
