None of these converswion factors would be used.

Answer 1

Here

Mile convert to meter (mans 1st convert mile to km than km to meter)

hour convert to second (means 1st convert in hour to minute than minute to second)

So the following conversion factors are used

(1.61 km / 1 mi) :- to convert mile to km

(1000 m / 1 km) :- to convert km to m

(60 min / 1 hr) :- to convert hr to minute

(60 s / 1 min) :- to convert minute to second

So all the conversion factors are used.
