Answer 2

Answer:

A train covers 383.8 km in $4\frac{3}{4}hr$

Step-by-step explanation:

Given that a train covers $80\frac{4}{5}km$ in 1 hr

we have to find the distance cover in $4\frac{3}{4}hr$

In 1 hr train covers $\frac{404}{5}$km

In $\frac{19}{4} hr$  train will cover

$=\frac{404}{5}\times \frac{19}{4}$

$=\frac{1919}{5}=383.8km$

Hence, a train covers 383.8 km in $4\frac{3}{4}hr$
