speeds, then find the ratio of the distances travelled by them in one hour.
3. If a car​

Answer 1

$\huge{\blue{\bold{\boxed{\ulcorner{\star\:Answer\: \star}\urcorner}}}}$

The ratio of their speed is 5:8

Given data :

Bus travels 160 kilometre in 4 hours.

Train travels 320 kilometre in 5 hours.

Bus Speed = 160/4 = 40 km/h

Train speed = 320/5 = 64 km/h

Ratio = 40 : 64

= 10 : 16

= 5 : 8 (answer)

Answer 2

$distance \: travel \: by \: bus \: in \: 4 \: hours = \\ 160km \\ distance \: travel \: by \: bus \: in \: 1 \: hours = \\ \frac{160}{4} </p><p>⇒40 \: km \\ \\ distance \: travel \: by \: train \: in \: 5 \: hours = \\ 320km \\ distance \: traveled \: by \: train \: in \: 1 hours = \\ \frac{320}{5} </p><p>⇒64 \: km \\ Now, </p><p></p><p>The \: required \: ratio \:  =d:D⇒40:64 \\ 5:8.</p><p></p><p>$
