Question

a train covers 80 4/5 km in 1 hr. how much distance will it cover in 4 3/4 hours/

Answer 1

the distance covered by a train in 1 hr = 80 4/5
distance covered in 4 3/4 hrs = 80 4/5 * 4 3/4 = 404/5 * 25/4 = 505

Answer 2

Distance covered by train in $\bold{4 \frac{3}{4}}$ hours is 383.3 km.

Given:

Distance = $80 \frac{4}{5}$km

Time = $4 \frac{3}{4}$

Solution:

A train takes 1 hour to complete a distance of $80 \frac{4}{5}$k m.

Let us take the distance to be covered = d.

To calculate the distance (d) covered in $4 \frac{3}{4}$  hours.

We calculate the amount of time it required to complete the distance in $4 \frac{3}{4}hour: 80 \frac{4}{5}$  km in 1 hour

So it would take $\bold{80 \frac{4}{5} \times 4 \frac{3}{4}=4.75 \times 80.8=383.8 \mathrm{km}}$
