Question

Aditya walks 3 km in 4 hours and vihaan walks 11 km in 2 hours find the ratio of their speeds.​

Answer 1

To find : ratio of speeds of Aditya and Vihaan.

Given : distance travelled by Aditya = $3 \ km$ and time taken = $4 \ hrs$

            distance travelled by Vihaan = $11\ km$ and time taken = $2 \ hrs$

• As we know formula to find speed is :

                   $speed = \frac{distance }{time}$  

• Therefore , speed of Aditya = $\frac{3\ km}{4\ hr}$

                                                       = $0.75 \ km / hr$

                           speed of Vihaan = $\frac{11\ km }{2\ hr }$

                                                        = $5.5 \ km/ hr$

• Now , ratio of their speed is : $\frac{speed of Aditya }{speed of Vihaan } = \frac{\frac{3}{4} }{\frac{11}{2} }$
• Taking reciprocal we get ,                           $= \frac{3}{4} \times \frac{2}{11}$

                                                                               $= \frac{3}{22}$

Hence , ratio of speed of Aditya  and Vihaan is $3 : 22$ .

Answer 2

Given,

Aditya walks $3km$ in $4$ hours and Vihaan walks $11km$ in $2$ hours

We have to the ratio of their speeds

First, we have to find the speed of Aditya and Vihaan

Formula,

Speed $= \frac{distance}{time}$

First we have to find the speed of Aditya

Here, distance $= 3km$, and time $= 4$ hours

Aditya's speed $= \frac{3}{4}$

Now,

Speed of Vihaan $= \frac{11}{2}$

Now, we have to written the ratio of speeds

$= \frac{3}{4}: \frac{11}{2}$

$= \frac{3}{2} : 11$

Take reciprocal, we get

$= 3:22$

Therefore, the answer is $3:22$.
