Answer 2

$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:

First look into length measurement table :-

• $\bold{\red{Kilometre}}↷×10$
• $\bold{\red{Hectometre}}↷×10$
• $\bold{\red{Decametre}} ↷×10$
• $\bold{\red{metre}}$
• $\bold{\red{Decimetre}}↺÷10$
• $\bold{\red{Centimetre}}↺÷10$
• $\bold{\red{millimetre}} ↺÷10$

Note : 1km=1000m and in 1 hour there is 60×60 seconds e.g 3600 seconds

For converting m/s into km/hr=>

$=>\bold{ \frac{m}{s} = \frac{ \frac{1}{1000} \times km}{ \frac{1}{3600} \times hr} }$

$\bold{= > \frac{m}{s} = \frac{3600 \times km}{1000 \times h}}$

$\bold{ = > \frac{m}{s} = \frac{18 \times km}{5 \times hr}}$

So,we have to multiply by 18/5 when we convert m/s into km/hr

$= > 50m/s = 50 \times \frac{18}{5} = 10 \times 18$

$\bold{\red{= > 180km/h}}$

when we have to convert km/hr into m/s

$\bold{=> \frac{km}{hr} = \frac{1000 \times m}{3600 \times s}}$

$\bold{= > \frac{km}{h} = \frac{5}{18} \times \frac{m}{s} }$
