Question

A train is running with the speed of 54 km/hour what is the speed in metre/ second.​

Answer 1

Aight multiply 5/18
Ya get 15m/s

Answer 2

To convert : speed of train $54$ km/hr  to meter /sec.

Solution :

• According to question we have to convert $54$ km/hr to 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 $=54 \times \frac{5}{18} (meter/second)$

                                 $=15 ( meter /seccond )$

Hence, conversion of speed of train $54$ km/hr  to meter /sec  is $15$ meter /sec.
