correct
bro i think the options are wrong
okkk
v1 = 60 km/hr t1 = 1 hr
x1 = vt = 60 km
v2 = 40 km/hr t2= 1/2 hr
x2= 20 km
vavg = x1 + x2 / t1 + t2 = 160 / 3 km/hr =53.3333333 km/hr
x1 = vt = 60 km
v2 = 40 km/hr t2= 1/2 hr
x2= 20 km
vavg = x1 + x2 / t1 + t2 = 160 / 3 km/hr =53.3333333 km/hr
this is the right answer
no no
okkkk
i am satisfied with your answer
