First distance= 200km
First speed= 300km/h
So, first time= distance/speed
=200/300
=2/3h
Second distance= 200km
Second speed= 240km/h
So, second time= distance/time
= 200/240
=5/6h
Hence average speed= total distance/total time
=200+200/2/3+5/6
=400/9/6
=400×6/9
=400×2/3
=800/3km/h
First speed= 300km/h
So, first time= distance/speed
=200/300
=2/3h
Second distance= 200km
Second speed= 240km/h
So, second time= distance/time
= 200/240
=5/6h
Hence average speed= total distance/total time
=200+200/2/3+5/6
=400/9/6
=400×6/9
=400×2/3
=800/3km/h

Hey Mate,☺️☺️
Here is your answer,☺️☺️
Speed=Distance/Time
1. Time=Distance/Speed
=200/300
=2/3hrs
=40min
2. Time=200/240
=5/6hrs
=50min
3. Total Time=40+50=90min=1.5hrs
Total Distance=200+200=400km
Avrage Speed=400/1.5=266.666...km/h
Hope it helps you a lot in you future.☺️☺️
THANK YOU MATE☺️☺️
