Sita travels 5 km to her school everyday by bicycle. She leaves her house at 7:00 am and reaches at 7:30 am. Find her speed?

Correct option is D

Given:
Distance traveled = 5 km
Time taken = 30 minutes = 0.5 hours
Formula Used:
Speed = $$\frac{\text{Distance}}{\text{ Time}}$$​​
Solution:
Speed = $$\frac{5}{0.5}$$​ = 10 km/h
So, Sita's speed is 10 km/h.
