Question

An aeroplane travel distance of 2500km , 1200km and 500km at the rate of 500km/hrs 250 hr / km respectively , find the a very garage speed of the plane

​

Answer 1

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 2

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
