Question

Please reply quickly .Ramesh travels from town A to town B at an average speed of 45 km/hr and returns at an average speed of 55 km/hr. If the total journey took 8 hours excluding stops, find the distance between Town A and Town B.

Answer 1

Answer: 198 km

Step-by-step explanation:

Let the total distance between the town A and B is x km,

According to the question,

He takes 8 hours in traveling from town A to town B at an average speed of 45 km/hr and returning at an average speed of 55 km/hr.

⇒ $\frac{x}{45} + \frac{x}{55} = 8$

⇒ $\frac{11x}{495} + \frac{9x}{495} = 8$

⇒ $\frac{20x}{495} = 8$

⇒ $x= \frac{3960}{20}=198$

Thus, the distance between town A and B is 198 km.
