You can put this solution on YOUR website! his rate is 625 miles per hour.
the number of seconds in on hour is equal to 60 * 60 = 3600.
the rate per second is therefore 625 / 3600 = .173611111..... miles per second.
there are 5280 feet in a mile, therefore the rate is .17361111... * 5280 = 916.6666666..... feet per second.
this could all be done in one shot by taking 625 and multiplying it by 5280 and then dividing it by 3600 to get 916.6666666... feet per second.
round to the nearest 10th to get 916.7 feet per second.

Look it up.
=================
I hope Rupert drove above 10,000 feet.
The speed limit below 10,000 feet is 250 knots, 288 mi/hr.
