Question

How much time will you save on a ten mile trip if you travel at 60 mph rather than at 55 mph

Answer 1

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
