### The motorist problem

By: The Marshmallows

• The question is : A motorcyclist could’ve completed the 900-mile trip in two hours less time if he had averaged 5 miles faster . What would be her/his average speed?

• Our hypothesis was a total 50 mph to complete it 2 hours faster.

Speed

Difference in time traveled in hours

The Equationspeed=distance/timeS+5mph=900 miles/(t-2hrs)where S= speed and T = time it took.

Plugging in the answer:45+5=900 miles/(20-2)simplifying:50=900/18Which is correct!
