Question

ANY BRAIN MASTER IS HERE TO SOLVE THIS QUESTION..??

The velocity of sound in air is 332m/s. If the unit of length is km and unit of time is hour, what would be the value of velocity?

Answer 1

1m = 10x^-3km; 332m = 332x10^-3 km
1sec = 1/3600hr

so the value would be,
332x10^-3/3600
= (83/9)10^-5

hence the value is, 83/9 (10^-5) km/hr

Answer 2

To solve the above, you need to convert m/s into km/h

the formula is to multiply the speed in m/s with 18/5.


so multiplying 332 with 5/18, we get

332*18/5=1195.2 kmph
