d=rt is the base formula for this. distance=rate×time The two known variables are the distance (10 miles) and the rate (55 or 60mph). There are two equations which can be formulated and solved for comparison. 10=55x 10=60x 10/55=x 10/60=x .187=x .167=x The last step is to convert the hours to minutes and minute remainders to seconds. .187×60minutes=10.07 .167×60minutes=11.22 1 minute, 9 seconds
