84 km / h in m / s plz help me<br>

PilotLPTM [1.2K]

Answer:

23 $\frac{1}{3}$ m/s

Step-by-step explanation:

We can change the km to m first. 1km = 1000m.

84km/h = 84 000m/h

Then, we can change the h to s. 1h = 3600s.

84 000m/h = 23 $\frac{1}{3}$ m/s

Usimov [2.4K]

Answer:

5 over 5

Step-by-step explanation:

You can see that 20x 5 is needed to get the denominator of 100, so you need to multiply the top by 5 too, to get 85/100. Hope this helps.
