Samaira cycled from her home to the hospital, then to the post office, then to the school and then she went back to her home. If she covered a total distance of 6.45 km, then what is the distance did she cover from hospital to post office?
A1.5 km
B1200 m
C0.9 km
D2300 m
The option which I selected was B. But when the result showed that I have clicked C. SOF has to take concern about this
