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.
10(.5x + 6) = 8
.5 can also be exchanged for a 1/2
To solve this, you can distribute the 10 and then subtract and divide, like so:
5x + 60 = 8
5x = -52
x = -10.4
