Answer 2

Answer:

Given,

Speed of car = x km/hr

Speed of train = (x+16) km/hr

And, we know that

Time = Distance / Speed

(i) Time taken by the car to reach town B from town A = 216/x hrs

(ii) Time taken by the train to reach town B from town A = 208/(x+16) hrs

(iii) According to the question, we have

x

216

=

x+16

208

=2

x(x+16)

216x+3456−208x

=2

x(x+16)

8x+3456

=2

4x+1728=x

2

+16x

x

2

+12x−1728=0

x(x+48)−36(x+48)=0

(x+48)(x−36)=0

x=−48,36

As speed cannot be negative,

=36

(iv) Therefore, the speed of the train is (x+16)=(36+16) km/hr = 52 km/h.
