I ibdutt Jul 2012 863 232 INDIA Dec 25, 2012 #2 2 miles in 13 minutes speed = distance / time = 2/13 miles per minute = 2/(13 x 60 ) miles per hour

B Bean Apr 2012 27 4 Maryland Dec 25, 2012 #3 Use ratios and cross multiply. \(\displaystyle \frac{2}{13} = \frac{x}{60} \) \(\displaystyle 13x = 120 \) \(\displaystyle x= \frac{120}{13} \)

Or, note that since there are 60 minutes in an hour, 13 minutes is 13/60 of an hour. Going 2 miles in 13/60 hour, you are going 2/(13/60)= 2(60/13)= 120/13 miles per hour.

Click to expand... Set up a ratio of "miles : minutes" 2 : 13 2/13 : 1 60 x 2/13 : 60 120/13 : 60 9.23 : 60 It's about 9.23 mph.

SVCrankson Mar 2013 4 0 Accra Mar 15, 2013 #7 firstly you will need to find the hours that were used. using the ratio minutes : hours 60mins = 1hr 13mins = 13/60 = 0.2166666666666667 then you have to find the speed which is the miles per hour speed = distance/time = 2/ 0.2166666666666667 = 9.230769230769229miles per hour you can round it up to 3sf making it; speed = 9.23mph
