Question

A body is moving with 54 km/hr then the velocity in m/s is ___________​

Answer 1

SOLUTION

TO FILL IN THE BLANK

A body is moving with 54 km/hr then the velocity in m/s is ______

EVALUATION

Here it is given that a body is moving with 54 km/hr

1 km = 1000 meter

1 hour = 3600 seconds

We have

$\displaystyle \sf{ = 54 \: \: km /hr }$

$\displaystyle \sf{ = \frac{54 \times 1000}{3600} \: \: m /s }$

$\displaystyle \sf{ = \frac{54 \times 10}{36} \: \: m /s }$

$\displaystyle \sf{ = \frac{540}{36} \: \: m /s }$

$\displaystyle \sf{ = 15 \: \: m /s }$

FINAL ANSWER

A body is moving with 54 km/hr then the velocity in m/s is 15 m/s

Answer 2

Here we have to convert the value of velocity from km/hr to m/s

In order to convert km/hr to m/s, we should know that the conversion factor is 5/18

For example, if we have to convert 18 km/hr into m/s We will have to multiply 18 by 5/18

therefore, 18 km/hr = $18\times\frac{5}{18}$ m/s

                               = 5 m/s

Now, 54 km/hr = $54\times \frac{5}{18}$

                          $=3 \times 5\\=15$

The answer will be 15 m/s
