Answer 1

Step-by-step explanation:

54 kilometers per hour = 1500 centimeters per second

So, 54 kilometers per hour = 54 × 27.777777777778 = 1500 centimeters per second

Answer 2

Question :-

Convert 54 km/hr to cm/sec

___________________

Solution :-

➲ Given Information :-

• Unit ₁ ➢ km/hr
• Unit ₂ ➢ cm/sec

➲ To Find :-

• 54 km/hr = ? cm/sec

➲ Concept :-

• Conversion of Units of Measurements

➲ Explanation :-

• A kilometer per hour is a unit of speed. Any body traveling at one kilometer per hour is traveling about 0.278 meters per second (approx.)

• A centimeter per second is also a unit of speed. Something traveling at one centimeter per second is traveling $\bf {( \frac{1}{100} )}^{th}$ of a meter per second.

➲ Calculation :-

∵ 1 km = 1,000 m

∴ 54 km = 54,000 m

AND,

∵ 1 m = 100 cm

∴ 54 km = 54,000 m = 54,00,000 cm

Now,

∵ 1 hour = 60 minutes

AND,

∵ 1 min = 60 seconds

∴ 1 hour = 3,600 seconds

Now finally, We know,

$\boxed{\rm{ \red{speed = \frac{distance}{time} }}}$

$\sf: \implies speed = \dfrac{5400000}{3600} = \blue{1500 cm/sec}$

∴ 54 km/hr = 1500 cm/sec
