Answer:
speed =distance/time. Here distance = 60+40(directly add the path length simply). and time =6+4=10s.so speed will be 100/10=10m/s. we know that velocity=displacement/time.displacement is shortest distance between the points so here it will be 70m.(note that 70 is shorter than 60+40) so velocity will be 70/10=7m/s

Answer:
70/10=7 m/s
Explanation:
60+40 (directly add the path length Simply ).and time = 6+4 10s. so speed will be 100/10=10 m/s .we know that velocity = distance between the point so here it will be 70 m. (note that 70 is shorter than 60+40 ) so velocity will be
70/10=7 m/s
