Question

Show that a speed of 31 m/s is less than a speed of 130 km/h

Answer 1

First, we need to convert kilometers per hour (km/h) to meters per second (m/s)

Step-by-step explanation:

m/s = 130 · 1000 ÷ 3600

130 · 1000 = 130000

130000 ÷ 3600 = 36.111

130 km/h = 36.111 m/s

Therefore, 31 m/s is less than 130 km/h or 36.111 m/s.

We already know that, but we still want to know what is 31 m/s in km/h right?

So, we need to convert m/s to km/h:

31 · 3.6 = 111.6

So, 31 m/s is 111.6 km/h, and 130 km/h is 36.111 m/s.

Hence, 31 m/s is less than 130 km/h.
