It depends on how long the object is. If the object is a dot, it will take 1.5 sec. This is not true, the size of the object is not important. If it is a car, a fly, or a plane it is all the same! If you take 90 mi/hr and multiple it by 5820ft you get ft/hour. This is 523800 ft/hr. Then divide this by 60 to get ft/min which is 8370, then divide it by 60 to get ft/sec., which is 145 ft/sec. Since you are only going 60 ft. divide 60/145 this is .41 sec. So it takes about a 1/2 sec. at 90 miles an hour to go 60ft.
