we know that
speed = (total distance)/(total time)
so, total distance =60+180+540+660
total distance =1440 mi
total time =10+30+90+110
total time =240 min
now, we can change time into hours
total time =
total time =4 hours
now, we can find speed
speed of the plane in miles per hour is 360 mph...........Answer
