Question

an object moves 360 km in 2hours . calculate its speed in km/h and M/s. ​

Answer 1

Explanation:

Given:-

an object moves 360km in 2hours

To calculate:-

Its speed in

• Km/h
• m/s

Solution:-

We know that

$\boxed{\sf Speed=\dfrac{Distance}{Time}}$

$\\ \sf{:}\longrightarrow\dfrac{ 360}{2}$

$\\ \bf{:}\longrightarrow 180km/h$

Again

We know that

1. 1km=1000m
2. 1hour=3600s

$\\ \sf{:}\longrightarrow 360km=360\times 1000=360000m$

$\\ \sf{:}\longrightarrow 2hours=2\times 3600=7200s$

$\\ \sf{:}\longrightarrow Speed=\dfrac{36000}{7200}$

$\\ \bf{:}\longrightarrow 50m/s$
