Answer:
She will take half an hour(30 min.) to reach office.
her avg. speed is 6mph.
Step-by-step explanation:
distance = speed * time
while running----
2= 8* t1
t1= 2/8= 1/4 hour.
while walking----
1=4*t2
t2=1/4hour
Total time = 1/4+1/4
= 1/2 hour
avg. speed= total distance
total time
= 3 = 6mph.
1/2
