							| Help 
 |  
							| My brain cannot work properly so please help me: is it correct to say " a cheetah runs 99 kph"  ? cause in my country we say "a cheetah runs with 99kmp"(in our mother tongue) and thus my confusion... |  10 Mar 2010

							| I think you shouldn �t use any preposition at all. Just say: a cheetah runs 99 kph, a tiger runs (up to) 35 mph. (up to - is optional, can say pretty much without it: a tiger runs 35 mph).

							| No preposition or "at". Both are correct, but it sounds better without a preposition.   Bruce |  10 Mar 2010

							| you don �t need to use  �at � in that sentence but �He was driving at a speed of 60km/h. �

							| Esoh - He was driving at a speed of 60 sounds really old-fashioned. 
 Today we just say - he was driving 60.

							| Thanks for letting us know libertybelle!! :)   It �s strange though that we can find sooooooooo many current results when we google �run at mph �. Maybe this prepositon �at � only sounds improper or old-fashioned to American ears?? ;))))))   |  10 Mar 2010

							| No I don �t think so topolina - downunder we say the same.  Although, I �d probably say he was going 60kmph or doing 60.  Spoken English today is much less formal than what it used to be. |  10 Mar 2010
