Question

a train cover 404/5 km in 1 hour how much distance will it cover in 19/4 hour

Answer 1

Since the train cover $\frac{404}{5}$ km in 1 hour.
So, the speed of the train = $\frac{404}{5}$ km/hr
And time = $\frac{19}{4}$ hours
So, total distance covered = $\mathrm{speed}\times \mathrm{time}=\frac{404}{5}\times \frac{19}{4}=\frac{1919}{5}=383.8\mathrm{km}$
Therefore total distance covered in the given time is 383.8 km.
