You can put this solution on YOUR website! A plane is travelling at 450 mph. It travels 10 miles. How long does it take to travel the distance?
-----------------
d = r*t
t = d/r
===============
Guessing is not the way to do it.
------------------
d = r*t = 450 mi/hr * 45 sec * 1min/60 sec * 1 hr/60 min
d = 450*45/3600 miles in 45 sec
d = 5.625 miles in 45 seconds.
