Distance=speed times time
distance/time=speed
distance=538
time=9 and 15mins
60mins=1hr
15/60=1/4=0.25
time=9.25hr
distance/time=538/9.25=58.162mph
about 58mph
        
                    
             
        
        
        
Answer:
129/2
Step-by-step explanation:
       1                129

To find the improper fraction, you multiply the denominator by the whole number and then add the numerator.  In the end, you put that answer over the starting denominator.
64 X 2 = 128      128 + 1 = 129     129 / 2 is the answer
