Question

i am trying to get an answer so give it to 

Answer 1

Speed is often given in miles per hour (of feet per second, or kilometers per hour, etc.).  Speed may change lots of times during a 2.3 hour period.  The average speed over that period is:

     300 miles per 2.3 hours

     300 miles  / 2.3 hours

     (300/2.3) miles/hour

      130 miles/hour     [130.4347826; note: this is the average, so rounding is o.k.]
