u=80 km/h=22.2m/s
v=60km/h=16.7m/s
avr. vel.=u+v/2
=22.2+16.7/2
=38.9/2
=19.45m/s
v=60km/h=16.7m/s
avr. vel.=u+v/2
=22.2+16.7/2
=38.9/2
=19.45m/s

wrong
u+v/2 is when body is moving with uniform velocity

hy there ✌
average velocity = displacement/time taken
80 km ___ 80 *18/5 = 288 m /s
60km = 60*18/5 = 216 m/s
now 288-216 /5 = 14.4 :)
