Question

. A car is running at 56 km/hr. what time will it take to cover 560 meters?

Answer 1

Answer:

v=56 km/h

S=560 m

=0.56 km

t=S/v

=0.56/56

=56/5600

=1/100 h

=0.01 h

Answer 2

Given:-

☛Speed= 56km/h

☛Distance covered = 560m

 

Find:-

☛Time Taken-?

 

Solution:-

First Convert km/h to m/s,

we know,

1km= 1000m

1h= 3600s

so,

$\sf{ \implies 1km/h = \dfrac{1000}{3600} m/s = \dfrac{5}{18} m/s }$

therefore speed =>

$\sf{ 56km/h = \dfrac{5}{18} \times 56 m/s= 15.55m/s}$

☛By using formula,

$\boxed{\bf{s= \dfrac{d}{t} }}$

where,

s= speed

d= distance

t=time

 

put values,

$\bf{\implies 15.55 = \dfrac{560}{t} }$

$\bf{\implies t= \dfrac{560}{15.55} }$

$\bf{ \implies t= 36.01 }$

Therefore, Time Taken by car is 36.01 seconds.
