Question

25 m/s convert into km / hr explain please​

Answer 1

1m = 1/1000 km

1hr = 60×60 s

so,

1s = 1/3600 hr

now,

1 m/s = (1/1000)÷(1/3600) km/hr

1m/s = (1/1000)×3600

25m/s = 3600×25/1000

= 90 km/hr

firstly convert meter and second into kilometer and hour respectively

then put these values at the place of meter and second

you have

$\frac{25 \: m}{s}$

put in it values of meter and second
