Question 209939
Step 1.  I assume you want to find which one has the greater velocity=distance/time.

Step 2.  

  a.  Distance Calculation.  1 and 1/4 is equal to 1.25=1+(1/4) where 1/4=0.25. Distance=1.25 miles.     


  b.  Time Calculation.  Time is 2 minutes and 4 secs=2*60 seconds+4 secs=124 seconds where 60 seconds=1 minute.


  c.  Velocity Calculation.  Velocity in miles per second=1.25 miles/124 seconds which is equal to about .010081 miles/sec=(0.010081 miles/sec)*(3600 sec/hour)=36.29 miles/hour where one hour=3600 seconds.



Step 3.  


   a.  Distance Calculation.  1 and 3/16 is equal to 1+(3/16)=16/16+3/16=19/16 miles. I put the fraction in a common denominator and 16/16=1. 



   b.  Time Calculation.  Time is 1 minute and 55 seconds=60 seconds+55 seconds=115 seconds where 1 minute=60 seconds.  


   c.  Velocity Calculation.  Velocity in miles per second is (19/16 miles)/(115 seconds)=  (0.010326 miles/second)*(3600 sec/hour)=37.17 miles/hour


Step 4.  Step 3c has the greater velocity than Step 2c.
