Question

a particle travels 24.6 km in 30 minutes pls tell me with the solution in km/h and m/s​

Answer 1

Answer:

The speed is $49.2 km/hr$

Step-by-step explanation:

A particle travels 24.6 km in 30 minutes.  

The distance $d = 24.6 km$

The time $t = 30 min$

Convert into hours,

$1min=\frac{1}{60} hrs$

$30 min=0.5 hrs$

The speed formula is given by,

$speed=\frac{distance}{time}$

$speed=\frac{24.6}{0.5}$

$speed = 49.2 km/hr$

Answer 2

Step-by-step explanation:

In 30 minutes the particle travels 24.6km

So in 60 minutes it will travel 2×24.6=49.2 km

So speed of the particle=49.2 km / h

49.2×5/18 m/s

=41/3 m/s or 13.6m/s (answer)
