Answer:
180km/hr
Explanation:
area of v-t graph gives displacement.
so area of v-t graph is = 2×1/2×50×100=5000
avg velocity= total displacement/ total time taken
= 5000/100= 50m/s=180km/hr
hope it helps ☺

ANSWER : HOPE IT HELPS YOU
STEP BY STEP EXPLANATION :
the velocity time graph of a particle moving in a straight line
V=U+at
U= 100m/s
AREA UNDER THE GRAPH = 1/2* B*H
1/2*100*100
5000
V = 100+ 5000
5100
