Answer:
If it helps mark me as brainliest.
Step-by-step explanation:
a)Two large squares on the x-axis show 15 min.
So, 1 large square shows 7.5 min.
She was stationary for 7.5 minutes.
b)Total distance= 25+ 25 km= 50 km
c)Distance travelled= 20 km.
Time= 30 min= 0.5 hrs
So, average speed
= 20/0.5
= 40 km/hr
