Answer:
12 dozens of donuts
Step-by-step explanation:
First, you want to change the decimal into a fraction. The decimal, 4.25, is the same as 4 25/100. You can reduce 4 25/100 to 4 1/4 by diving both the numerator and denomiator by 25. Now that both of our numbers are fractins, we can just add the fractions up. 7 3/4 + 4 1/4 = 11 4/4 = 12\

Remark
Average Speed = Total distance divided by total time.
Total Time
2 hours + 3 hours = 5 hours. The total time is 5 hours.
Total Distance
d = rate * time
d1 = 40 km/hour * 2 hours = 80 km
d2 = 50 km/hour * 3 hours = 150 km
d = d1 + d2
d = 80 + 150 = 230 km
Average Speed
Av = Total distance / Total Time = 230 / 5 = 46 km/hr
