Answer:

37.86 mph and 40.86 mph

Step-by-step explanation:

The speed for the first session is x, for the second session will be x+3

Average speed= (x+x+3)/2= x+1.5

Total distance covered will be 228+205=433 miles

Time= 11 hours

Time= Distance/ speed

Speed= distance/time

Average Speed= 433/11

x+1.5=433/11

x+1.5=39.36363636

x=39.36363636 -1.5= 37.86363636

Approximately, x= 37.86 mph

x+3=37.86+3= 40.86 mph
