#### Only one of the four options is correct. Write the correct one.If a bus travels 160 km in 4 hours and a train travels 320km in 5 hours at uniform speeds, then the ratio of the distances travelled by them in one hour is(A) 1 : 2 (B) 4 : 5 (C) 5 : 8 (D) 8 : 5

Given: Distance travelled by bus in 4 hours =160 km

Distance travelled by bus in 1 hour = $\frac{160}{4} \mathrm{~km}=40 \mathrm{~km}$

Distance travelled by train in 5 hours =320 km

Distance travelled by train in 1 hour = $\frac{320}{5} \mathrm{~km}=64 \mathrm{~km}$
The ratio of the distances travelled by bus and train in one hour is

$\frac{40 \mathrm{~km}}{64 \mathrm{~km}}=\frac{5}{8}\Rightarrow 5: 8$

Option C is correct.
