Answer 2

Given,

A train covers 404/5km in = 1 hour

or We can write it as =>

In one hour a train covers = 404/5km

=>In one hour a train covers = 80.5km

Hence in in 19/4 hours the train will cover

=(19/4)× 80.5

=383.8 km

Hence, the train will cover exactly 383.8 km in 19/4 hours at an speed of 80.5km/hour.



Some more information=>

1)We have actually used unitary methord to solve this maths

2)It is actually an algebraic technique in which first we find the value of single unit or 1 then multiply the required value with the 1.

3) Always remember some formulas while doing these types=>

Speed = Distance/time
