420Km/hr (Given the rate of speed is 500, 400, 250kmph)

Step-by-step explanation:

Average speed = Total Distance/ Total time.

Let's find out the total time taken by the aeroplane in each of the journey.

2500km at the rate of 50kmph = 50 Hours

1200km at the rate of 400kmph = 3 hours

500km at the rate of 250kmph = 2 hours

Average Speed = (2500+1200+500) / (50+3+2) = 76.6 Km/hr

I guess you made a typo, the first speed mentioned is to be 500kmph instead of 50kmph, in that case 2500km at the speed of 500kmph will take 5 hours to cover.

Then, Average speed will be = 4200/ 5+3+2 = 4200/10

= 420Km/hr.

Answer:

76.363

Step-by-step explanation:

average speed = total distance / total time

total distance = 2500+1200+500 = 4200

total time = 2500/50 = 50 , 1200/400 = 3 , 500/250=2

total time= 50+3+2= 55

average speed= 4200/55 =76.363
