a.divide 100 by 1.609
b.multiply 100 by 1.609
c.multiply 100 by 3.281
d.divide 100 by 3.281

Answer 1

multiply 100 by 1.609

Answer 2

a.divide 100 by 1.609

Explanation:

We know the relation between miles and kilometers

1 mile = 1.609 km

Now, we have to convert 100 km to miles.

Let x miles in 100 kilometers.

Hence, we have

`(1)/(1.609)=(x)/(100)\\\\x=(100)/(1.609)`

Therefore, we can see that we have divided 100 by 1.609 in order to find the number of miles in 100 km.

Therefore, a is the correct option.
