Answer:
v=1.132m/s
Step-by-step explanation:
velocity=total distance/ total time
first convert 1km to m so that would be 1000m then add the total distance so 200+1000=1200. 1200 is the total distance. now add the total time so we need to convert 15 min to sec which is 900 sec. 160 +900=1060. now divide total distance by total time.
v=?
d=1200m
t=1060s
v=d/t
v=1200m/1060s
v=1.132m/s
