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= ![speed\times time](https://tex.z-dn.net/?f=speed%5Ctimes%20time)
1st trucker, distance
∴ ![d_1= 62x+62](https://tex.z-dn.net/?f=d_1%3D%2062x%2B62)
2nd trucker, distance![(d_2)= 66\times x](https://tex.z-dn.net/?f=%28d_2%29%3D%2066%5Ctimes%20x)
∴![d_2= 66x](https://tex.z-dn.net/?f=d_2%3D%2066x)
Now, putting the values in an equation.
![d_1+d_2= 270](https://tex.z-dn.net/?f=d_1%2Bd_2%3D%20270)
⇒ ![(62x+62)+66x= 270](https://tex.z-dn.net/?f=%2862x%2B62%29%2B66x%3D%20270)
Opening the parenthesis to solve and subtracting both side by 62
⇒ ![122x= 208](https://tex.z-dn.net/?f=122x%3D%20208)
∴ x=
= 1 hour 42 minutes
∴ It will take 1 hour 42 minutes to be able contact each other after first trucker leaves.

Answer:
Step-by-step explanation:
Let x represent the larger number.
Let y represent the smaller number.
The sum of two numbers is thirty seven. This means that the smaller number would be 37 - x
The translation into a variable expression for the the difference between nine more than twice the larger number and the sum of the smaller number and three would be
2x + 9 - (37 - x + 3)
Opening the parenthesis and putting the constants together, it becomes
2x + 9 - 37 + x - 3
2x + x + 9 - 37 - 3
3x - 31
