Question

Ravi is the fastest of all. He can travel with the double speed as Vijay. How far can he go in 4 second?​

Answer 1

Given :

$\textsf{Vijay travel 169m in 13s}$

$\textsf{Tilak travel 26m in 2s}$

$\textsf{Ravi travel double speed as Vijay}$

To find :

$\textsf{How far Ravi can travel in 4s}$

Concept :

So , to find the distance travelled by Ravi in 4s . Use this formula -:

$\sf{D=S\:\times\:T}$

Where,

D = Distance

S = Speed

T = Time

A/Q

Speed is not given . And the time is given which is 4s.

And in the question there is given that Ravi travel double speed as Vijay . So , we have to first find the speed of Vijay in m/s . And then we have to do the double of the speed and then use the distance formula to find the distance travelled by Ravi .

So , to find the speed . Use this formula -:

$\sf{S=\dfrac{D}{T}}$

Solution :

Speed of Vijay in m/s -:

$:\implies\sf{S=\dfrac{\cancel{169m}}{\cancel{13s}}}$

$:\implies\sf{S=13m/s}$

So , the speed of Vijay in m/s is 13 m/s .

Now , do its double -:

$:\implies\sf{S=13m/s\times2}$

$:\implies\sf{S=26m/s}$

So , now we have got the speed of Ravi in m/s .

Distance travelled by Ravi -:

$:\implies\sf{D=26m/s\times4s}$

$:\implies\sf{D=104m}$

So , the distance travelled by Ravi in 4s is 104m .

Answer :

Distance travelled by Ravi = 104 m
