Question

Using the information given in the image,
What is the length of the truck?
12 m
18 m​

Answer 1

Answer:

15

Step-by-step explanation:

let the length of car be x and bike be y.

truck length(side-1) = 12-y+x

truck length (side-2) = 18-x+y

truck length(side-1) = truck length(side-2)

12-y+x = 18-x+y

x = 3-y.

putting x value in truck length(side 1 or 2), we get 15m length.

Answer 2

Length of truck = 15m

Step-by-step explanation:

Let the length of car be x and bike be y.

Truck length (from its left) = 12 -y + x -----------------(1)

Truck length (from its right) = 18 -x + y ---------------(2)

Truck length is equal on both its sides.

So we get:

12 - y + x = 18 - x + y

2x - 2y = 6

x = 3 + y --------------(3)

Substituting 3 in 1, we get:

Truck length = 12 - y + 3 + y = 15 m
