Question

a train at a uniform speed cover a distance of 255 km in 3/2 hours.find the speed of the and the distance coverrd in 19/5 hour

Answer 1

Answer:

The speed and distance is 170 km/hr and 646 km respectively.

Step-by-step explanation:

Given that a train at a uniform speed cover a distance of 255 km in 3/2 hours.

we have to find the speed of the train and the distance covered in 19/5 hours

As

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

$Speed=\frac{255}{\frac{3}{2}}=170 km/h$

As train at uniform speed remains constant

∴ Speed=170 km/hr

Now, we find the distance covered in 19/5 hours

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

$170=\frac{Distance}{\frac{19}{5}}$

$Distance=170\times \frac{19}{5}=646 km$

The speed and distance is 170 km/hr and 646 km respectively.

Answer 2
