MODEL 1

Speed

Difference in time traveled in hours


The equation speed distance time s 5mph 900 miles t 2hrs where s speed and t time it took
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 18 which is correct
Plugging in the answer:45+5=900 miles/(20-2)simplifying:50=900/18Which is correct!
