Question

Convert an acceleration of 20m/s² into km/hr²

Answer 1

Answer:

259200 km/hr^2

Explanation:

20 m = 20/1000 km

= 1/50 km

1 s^2 = 1/3600^2

20 m/s^2 = (1/50)/(1/3600)^2

= 259200 km/hr^2

Answer 2

I hour = 3600 sec

I km = 1000 meters

To convert we should simplify 3600/1000 = 18/5

20*18/5=72kmph
