V = d/t
d = vt
let ,
v1 = 60mil/hr. V2 = 50mil/hr
t1 = 3hr. t2= 4hr
average speed = total distance travelled/total time taken
Va = d1+d2/t1+t2
Va = v1t1 + v2t2/t1+t2
Va = 60×3 + 50×4/3+4
Va = 180+200/7
Va = 380/7
Va = 54.3mil/hr

Hey bro! here is ur ans. t1 = 3; t2 = 4 s1 = 60 m/s. ; s2= 50 m\s average speed = (60 + 50) / (3+4) = 110 / 7 = 15.5555.. m/s
