Question

which of the two speeds is greater 20m per second or 90km per hour?

Answer 1

Answer:

90km/h

Step-by-step explanation:

you can convert Km/h to M/s and then compare!

the simplest way to do so is multiply the speed (km/h) with 5/18 to get the speed in m/s

and i u want to convert m/s to km/h, multiply speed(m/s) with 18/5.

now ur question,

90 km/h = 90x5/18= 5x5=25 m/s

thus, 90km is greater than 20 m/s

hope it helped
