Answer 1

Answer:

. 35.56 m/s

4. 150 nm

5. 218, 400 sqm

Step-by-step explanation:

3.

= \frac{128 \: km}{hr} \times \frac{1 \: hr}{3600 \: s} \times \frac{1000 \: m}{1 \: km}=

hr

128km

×

3600s

1hr

×

1km

1000m

= 35.56 m/s

4.

= 0.15μm \times \frac{1000 \: nm}{1 \: μm}=0.15μm×

1μm

1000nm

= 150 nm

5.

A= l x w

A = (5 x 105 m) x (4 x 104 m)

A = (525 m) x (416 m)

A = 218,400 sqm

The importance of having a standard in measurement is it allows us to have a common reference point as there are different ways objects are measured. Standard unit in measurement also reduces confusion and mistakes when communicating measurements with others.
