Question

Aree yrr krdo koii solve please...

Answer 1

Air distance between kota&jaipur =260km
Road distance between kota&jaipur=320km
Total time taken by bus=8h
Total time taken by aeroplane=15 min=0.25h
1).average speed of bus in km/h
=Total distance travelled /Total time taken
=320/8=40km/h.
2).Average velocity of bus in km/h
=initial velocity=u=0km/h
=Final velocity=v=40km/h.
=(u+v)/2=(0+40)/2=40/2=20km/h
3).average speed of aeroplane in km/h
=Total distance travelled/Total time taken
=260/0.25=1040km/h.
4).Average velocity of aeroplane in km/h
=initial velocity=u=0km/h
Final velocity=v=1040km/h.
=(u+v)/2=(0+1040)/2=1040/2=520km/h.


I hope its help you .
