Question

A train travelling at uniform speed covers adistance of 255 km in 3/2 hours. Find the speed of the train and the distance covered in 19/5 hours .

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=timeDistance

Speed=\frac{255}{\frac{3}{2}}=170 km/hSpeed=23255=170km/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}Speed=timeDistance

170=\frac{Distance}{\frac{19}{5}}170=519Distance

Distance=170\times \frac{19}{5}=646 kmDistance=170×519=646km

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