Answer 2

Answer:

90 km/h is the greatest.

Explanation:

First we can keep the 20m/s as it.

Now lets convert 90km/h into m/s.

for converting km/h to m/s we need to multiply the number with 5/18.

Now, 90*5/18

=5(5)

=25m/s

Therefore you know that 20m/s is less than 25m/s.

Therefore 90km/h is greater than 20m/s.
