The micrometer (1 μm) is often called the micron. (a) how many microns make up 2.4 km? (b) how many centimeters equal 2.4 μm? (c) how many microns are in 2.4 yd?

(a)

(B)

(C)

Explanation:

We have given 1 micrometer is called 1 micrometer

So

(A) We have given 2.4 km

We know that 1 km = 1000 m

So 2.4 km = 2400 m

As

So in 2400 m  

(B) We have given 2.4 micrometer

We know that

So

As we know that 1 m = 100 cm

So

(C) We know that 1 yard = 0.9144 m

So 2.4 yard will be equal to

As

So 2.194 m
