Answer 1

Question :-

find the speed of a car in metres per second if it's speed is 48 km per hour.

Solution :-

Given :

• Speed : 48km/hr

Need to find :

• Convert into m/s

We know,

1km = 1000m

1hr = 3600sec

Hence,

48km = 48000m

1hr = 3600sec

Now,

→ 48000/3600

→ 480/36

→ 40/3

→ 13.333

Answer : 13.33m/s

Answer 2

GIVEN :-

Speed = 48 km/h

TO FIND :-

Conversion of 48 km/h into m/s

SOLUTION :-

We know that,

$\sf \fbox \orange{1km = 1000 \: m}$

$\sf \fbox \orange{1hr = 3600 \: sec}$

Hence,

$\sf 48km = 48000m$

$\sf 1hr = 3600sec$

Now, to convert km/h into m/s divide the distance and time.

$\sf →\frac{48000}{3600}$

$\sf → \frac{480}{36}$

$\sf → \frac{40}{3}$

$\sf \fbox \green{→13.333 \: m/s}$

$\therefore$ 48 km/h in metres per second is 13.333 m/s.
