Question

A train covers $\dfrac{404}{5}$ km in 1 hour. How much distance will it cover in $\dfrac{19}{4}$ hours?

Answer 1

Distance of the train = $\frac{404}{5}km$

Time taken by the train = 1 hr .

$Speed=\frac{Distance}{Speed}$

$\implies Speed=\frac{\frac{404}{5}}{1}km/hr$

$\implies Speed=\frac{404}{5}km/hr$

Time = $\frac{19}{4}hr$

Speed = $\frac{404}{5}km/hr$

$Speed=\frac{Distance}{Time}$

$\implies Distance=speed\times time$

Using the above formula we get :

$\implies Distance=\frac{19}{4}\times \frac{404}{5}km$

$\implies Distance=\frac{7676}{5}km$

$\implies Distance=1535.2km$

The distance will be 1535.2 km .

Answer 2

Answer:

= 383.8 km.

Step-by-step explanation:

Given, speed of the train = 404/5

          Time = 19/4 hr

We know that distance = speed * time

                                      = 404/5 * 19/4          

                                     = 1919/5

                                          = 383.8 km.
