Answer:
Please find solution in the picture attached
Step-by-step explanation:
Its c first find area of the whole thing with piece cut out.(240) then of the cut out piece (12) 240-12=228 C
Time for first plane = 625 / 250
= 2.5 hours
after 1.25 hours
boeing 747 takes 1.25 hours (2.5 - 1.25) to arrive at the same location at the same time
so, speed = distance / time
= 625 / 1.25
= 500
the average speed of the boeing 747 is 500 mph
