Answer:

10 m/s

Step-by-step explanation:

$&#10230 \: \: 72 \: km {h}^{ - 1} \\ \\ &#10230 \: \: \frac{72 \times 10\cancel{00}}{6\cancel0 \times 6\cancel0} \\ \\ &#10230 \: \: \frac{72 \times \cancel{10}}{\cancel{36}} \: \: \: \: \\ \\ &#10230 \: \: \frac{\cancel{72} \times 5}{\cancel{18}} \: \: \: \: \: \\ \\ &#10230 \: \: 4 \times 5 = 10$

• 20 m/s

Answer 2

72 km per hour
So m/s =?
= 20 m/s

1 km =1000m
1 hour =3600s
72*1000/3600

0 cancel so it is

72*10/36

2*10/1
2*10
=20
