Answer 1

Answer:

O km per hour

........................

Answer 2

The distance between her school to home is 300 meters, then her speed is 0.6 km/hr.

Explanation:

The student started school from home at 9:00 a.m.

And, reached school by 9:30 a.m.  

So, time taken to travel from home to school = 30 minutes = $\frac{30}{60}$ hr = 0.5 hr

Distance between the school and home = 300 meters = $\frac{300}{1000}$ km = 0.3 km

The formula for speed is given by,

Speed = [Distance] / [Time]

Substituting the values in the formula,

Speed = $\frac{0.3}{0.5}$ = 0.6 km/hr

Thus, her speed for travelling from home to school is 0.6 km/hr.
