Answer 1

Given:

Distance between head of yellow racing car and tail of red racing car is 12 m and 18 m respectively.

To Find:

What is length of truck?

Solution:

Let:

Length of red car = a

Distance between head of yellow and red car = b

Length of yellow car = c

Distance between tail of yellow and red car = d

Now from figure, it is clear that:

Length of truck = c + b = a + d              ...1)

From question, it is given that:

a + b = 12                             ...2)

d + c = 18                             ...3)

On adding equation 2) and equation 3), we get:

a + d + b + c = 12 + 18

(a + d) + ( c + b) = 30           ...4)

From equation 1) and equation 4):

(a + d) + ( c + b) = 30

(a + d) + (a + d) = 30                (∵ c + b = a + d )

2(a + d) = 30

So:

a + d = 15 = c + b

Means length of truck is 15 metre.

Answer 2

Answer:15 m

Step-by-step explanation:

Let's T=truck, B=bike, C=Car

T+B-C=12....

T+C-B=18....

2T = 30...

So, answer is T = 15 m
