Allison walks three fourths of a mile in three tenths of an hour. What is his speed in miles per hour?

Oct 19th, 2017

3/10 of an hour = (3*60 min)/10 = 18 minutes

3/4 mile per 18 minutes = 0.75/18 = 75/1800 (to get rid of the decimal)

75/1800 = x/6000

x = 250 now we must move the decimal point back to get 2.5 miles/hr
