Question

convert 54km/hr into m/s​

Answer 1

Answer:

54km/hr = 15m/s

Step-by-step explanation:

To convert km/hr to m/s is to multiply the number with 5/18=

=54 x 5/18

=3 x 5

=15 m/s

Answer 2

To convert : $54 \mathrm{~km} / \mathrm{hr}$  to meter /sec.

Solution :

• According to question we have to convert to  $54 \mathrm{~km} / \mathrm{hr}$  to meter /sec. meter /sec.
• As we know, $1 (kilometer/hour )=1000( meter ) / 3600( second )$  which can also be expressed as $1 (kilometer/hour) =\frac{5}{18} ( meter/second)$ which is simplified form.
• Therefore, to convert we directly multiply given value of speed by the fraction $\frac{5}{18}$ .
• Hence, we get  $54\ km / hr =54 \times \frac{5}{18} (meter/second)$

                                                   $= 15 ( meter / seccond )$

Hence, conversion of  $54 \mathrm{~km} / \mathrm{hr}$  to meter /sec  is $15 m/s$ .
