average speed.. = total distance/ total time
= hypotenious/2s
h²=12²+5²
144+25
169=13²
h=13
so average speed = 13/2= 6.5m/s
average velocity= U+v/2
0+6.5/2
3.25m/s

Your answer is wrong the answer will come 17:13 but how i don't know
soory but.. average velocity ka formula kiya tha
bcz average speed is right...
their is something wromg with average velocity
