Step-by-step explanation:
(55 km/h) * (1 mi)/(1.609344 km) ≈ 34.2 mi/h
_____
You can do units conversions pretty easily by multiplying by a conversion factor whose value is 1. That is, since
.. 1 mi = 1.609344 km
dividing by the left side we have
.. (1 mi)/(1.609344 km) = 1
This factor has the convenience that it will cancel km and give mi when multiplied by some number off km. That is what we did above. (The "per hour" just went along for the ride. It did not get involved in the units conversion.)
84
84 = 42 x 2
The greatest common factor is 42, because 84/2 = 42, & you want the biggest number possible
Usually i need two or more numbers so.. this is the best i can get out of one number
hope this helps tho :D

Don't expect people to help solve a problem like that if it looks like you gave no thought in posting it
