Answer: a) 0.5; b) 0.667; c) 0.6 miles / minute

Step-by-step explanation:

a) Average speed = total distance / total time = 10/20 = 0.5 miles/min

b) Average speed = total distance / total time = 20/30 = 0.667 miles/min  

c) Average speed = total distance / total time = (10+20)/(20+30)

= 30/50 = 0.6 miles/min
