Question

3. A student walks from his house at 7:45 a.m. and reaches his school at 9:15 a.m. The
of the school from his house is 12 km find its speed​

Answer 1

Answer:

To find the time we should subtract the final time from initial time = 9:15-7:45.

The time gap between them is 1h 30 minutes=1.5hours.

Distance is given as 12km.

So, speed= distance/time=12/1.5=8km/hr.

Speed of the student=8km/hr.
