Answer:
first lets find the total hours of the journey
time = distance / speed
2500/500 = 5 , 1200/400 = 3 , 500/250 = 2
total time was 5 + 3 +2 = 10 hours,
now calculate total distance --> 2500 + 1200 + 500 = 4200
average speed = distance / time
= 4200/10
= 420 km/hr

Answer: 420 km/h
Step-by-step explanation: for 2500 km, time needed = 2000km ÷ 500km/hr = 5hr
for 1200 km, time needed = 1200km ÷ 400km/hr = 3hr
for 500 km, time needed = 500km ÷ 250km/hr = 2 hr
total time needed = 10hr
total distance = 2500km+1200km+500km = 4200km
average speed = 4200km ÷ 10hr = 420km/hr
Hope it helps you! :)
