Answer 1

80 km/ph

Step-by-step explanation:

doble.

2×40 km ,hr

80 km/hr

Answer 2

Given:

Ram takes double the time by train to travel from Banglore to Chennai than by bus

The speed of the bus = 40km/hr

To Find:

The speed of the train

Solution:

The distance between Banglore and Chennai is constant. Let it be d.

We know that speed = Distance / Time

Let the time taken by Ram to reach Chennai via Bus and Train be tb and tt respectively.

Let the speed of the train be V

⇒ 40 = d / tb

and V = d / tt

Dividing the above equations,

$\frac{40}{V} = \frac{tt}{tb}$       - (1)

Since the time by bus is double the time by train,

⇒ tb = 2 X tt

Substituting in equation 1,

$\frac{40}{V} = \frac{tt}{2 X tt}$

or V = 40 X 2

= 80 km/hr

Hence, the speed of the train is 80 km/hr.
