Answer:
400m/s
Step-by-step explanation:
2hrs 15 minutes is equal to 120+15 minutes=135 minutes
135 minutes = 135*60 seconds= 8100 seconds
3240 km=3,240,000 m
speed =distance/time
speed =3,240,000/8100
speed =400m/s
Alternative Method:
2hrs 15 minutes=2.25 hrs
speed=distance/time
speed=3240/2.25
speed=1440km/h
1m/s= 3.6km/h, so 1440km/h= 1440/3.6m/s=
400m/s
