Question

If Raju cycles 40km in 5 hours and Shalu cycles 36 km in 4 hours , then the ratio of Raju speed to Shalu speed is
A. 10 :9
B. 9:10
C. 9:8
D. 8:9

Answer 1

Raju's speed,

$x = \frac{40}{5}$

$x = 8$

shalu's speed,

$y = \frac{36}{4}$

$y = 9$

therefore,

ratio,

$= \frac{x}{y}$

$= \frac{8}{9}$

=8:9

Answer 2

In case of Raju,

$\bold{=> Speed= \dfrac{Distance}{Time}}$

$\bold{=> S= \dfrac{40}{5}}$

$\bold{=> S= 8 \: Km{h}^{-1}}$

Again,

In case of Shalu,

$\bold{=>S'= \dfrac{D}{T}}$

$\bold{=> S' = \dfrac{36}{4}}$

$\bold{=> S' = 9\: Km{h}^{-1}}$

Ratio,

$=> \dfrac{S}{S'} = \dfrac{8}{9}$

$=> \bold{S:S' = 8:9}$
