Question

a motorbike is moving at a speed of 10 metre per second what will its speed be in kilometre per hour​

Answer 1

★ 36 km/h ★

Given ,

• Speed of motorbike = 10m/s

We need to find ,

• Speed in km/h

As we know that,. to convert m/s to km/h , we need to multiply with 18/5 .

So ,

=> 10m/s × 18/5

=> 3.6 × 10

=> 36 km/h

Hence , 10 m/s = 36 km/h

♦ Why should we multiply with 5/18 to convert in km/h :-

Because , here km = 10³ m & h = 3600s

By substituting ,

• km/h = 10³ m/3600s
• km/h = 1000m/3600s
• km/h = 10m/36s
• km/h = 5/18 m/s

So , 1 km/h = 3.6 m/s

Answer 2

Question :-

→ A motorbike is moving at a speed of 10 metre per second what will its speed be in kilometre per hour​

Given :-

→ Speed of motorbike in m/s = 10 m/s

To Find :-

→ Speed of motorbike in km/hr

Solution :-

→ As we know that ,

to convert m/s into km/hr we can multiply it by $\dfrac{18}{5}$

→ Let's solve !!

$\sf \rightarrow \dfrac{18}{5} \times 10 \\\\\\\rightarrow 18 \times 2 \\\\\rightarrow 36 \; km/hr$

∴ A motorbike's speed in km/hr will be 36 km/hr

All Done !! :D
