Question 1064063
.
Two students Bert and Sol left the same house at the same time. They both walk to school. 
Each step of Bert is 20% shorter than each step of Sol, however, the number of steps Bert takes is 20% more then the number of steps 
Sol takes in the same amount of time. Who will get to the school faster?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Let "n" be the number of steps Sol makes in 1 minute, and let "s" be the length of his step (in meters).


Then Sol's rate (speed) is n*b meters per minute.


Regarding Bert, he makes 1.2*n steps per minute, but each his step has the length 0.8s, 

          so his rate (speed) is 0.8n*1.2s =  0.96ns meters per second.


Now you see that Bert moves slower than Sol, and the answer is clear to you.


<U>Answer</U>.  Who will get to the school faster? - Sol will.
