Question

A car travelling with the speed of 252/5 km per hour. How much time will it take to travel the distance of 200 km.

Answer 1

GIVEN:

• Speed of the car (s) = 252/5 km/hr.
• Distance travelled (D) = 200 km

TO FIND:

• What is the time taken by the car ?

SOLUTION:

Let the time taken by the car be 'T' seconds

We know that the formula for finding the time taken is:-

$\large{\boxed{\bf{\star \: TIME = \dfrac{DISTANCE}{SPEED} \: \star}}}$

According to question:-

On putting the given values in the formula, we get

$\sf{\longmapsto T = \dfrac{200}{\frac{252}{5}} }$

$\sf{\longmapsto T = \dfrac{200 \times 5}{252} }$

$\bf{\longmapsto T = 3.96 \: seconds }$

• TIME TAKEN = T = 3.96 seconds

❝ Hence, the time taken by the car is 3.96 seconds ❞

Answer 2

QUESTION:-

A car travelling with the speed of 252/5 km per hour. How much time will it take to travel the distance of 200 km.

ANSWER✓

$\Large\bold{given,}$

$\sf\dashrightarrow speed(S)= \dfrac{253}{5} \frac{km}{hrs}$

$\sf\dashrightarrow distance\:travelled(D)=200km$

$\Large\bold{TO\:FIND,}$

$\sf\dashrightarrow TIME\:TAKEN\:BY\:THE\:CAR\:TO\:REACH\:THE\: DESTINATION$

$\Large\underline\bold{SOLUTION,}$

$\therefore let\:us\:assume\:that\:time\:taken\:by\:the\:car\:is\:T\:sec$

$\sf\large\bold{now}$

$\sf ATQ...i.e.,...........according\:to\:the\:question$

$\sf\: therefore to\:find\:the\:value\:of\:T,$

$\Large\underline\bold{formula\:used}$

$\sf\therefore time = \dfrac{distance}{speed}$

$\Large\underline\bold{now,}$

$\sf{\therefore t = \dfrac{200}{\frac{252}{5}} }$

$\sf{\therefore t = \dfrac{200 \times 5}{252} }$

$\sf{\therefore t = \dfrac{1000}{252} }$

$\sf{\therefore t = \dfrac{250}{63} }$

$\sf{\therefore t= 3.96 \: seconds }$

$\large{\boxed{\sf{TIME = 3.96sec}}}$

time taken = T = 3.96 sec

HENCE,

TIME REQUIRED TO TRAVEL THE DISTANCE OF 200 KM =3.96 SEC
