Answer 1

Answer:

Delhi and Banglore - 1200Km = Airplane (2 hours)

                                  - 1500km = train (25 hours)

Airplane ( 1200km divided by 2 hours) 600km/h

train ( 1500km divided by 25 hours) 60km/h

the average speed

600km/h + 60 km/h = 660km/h

Pls mark my answer the brainliest and this questions subject is science because year6 science has a topic of speed.

Answer 2

Answer:

averagea speed =total distance /total time

case 1 (air) total distance = 1200 km

total time = 2 hrs

average speed =1200 km / 2 hrs

= 600 km / hr

case 2 (train)

total distance = 1500 km

total time =25 hrs

average speed = 1500 km / 25 hrs

= 60 km /hr

the average speed = 660 km / hr
