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.

Given :The scented burns inches in 20 minutes
The scented candle will burn inches in one hour.
The unscented candle burns inches in 30 minutes
In one hour it will burn inches .
Burn rate of scented is inches per hour.
Burn rate of unscented is inches per hour.
We know, Distributive property tells:
a(b + c) = ab + bc
Here, GCD of 27 & 60 is 3, so take it as a common factor,
=3(9 + 20)
In short, Your Answer would be: 3(9 + 20)
Hope this helps!
