Question

A particle travels 24.6 km in 30 minutes. Find the
speed of the particle in
(i) km/h,
(ii) m/s.​

Answer 1

The speed is 49.2 km/hr.

Step-by-step explanation:

Given : A particle travels 24.6 km in 30 minutes.

To find : The speed of particle in km/h ?

Solution :

The distance is d=24.6 km

The time is t=30 minutes

Convert into hours,

1\ min=\frac{1}{60}\ hr1 min=

60

hr

30\ min=0.5\ hr30 min=0.5 hr

The speed formula is given by,

\text{Speed}=\frac{\text{Distance}}{\text{Time}}Speed=
