Two hours.

Time is given by the following equation:

#t=d/s#

where #s# is the speed of the object, #d# is the distance that the object has travelled.

So, plugging in the values, we get

#t=(90color(red)cancelcolor(black)"miles")/(45color(red)cancelcolor(black)"miles""/h")#

#=2 \ "h"#

So, it'll take the object #2# hours to travel #90# miles at a speed of #45# miles per hour.
