Answer:

6 km/h

Step-by-step explanation:

Leaves house: 9:30 am

Distance to school: 2 km

Start of class: 10:00 am

Speed for 1st kilometer = 3 kph

Time taken for 1st km = Distance / Speed = 1/3 of one hour = 20 minutes

Time at end of 1st km = 9:50 am

Distance left to travel = 1 km

Time left = 10 min = 1/6 of one hour

Speed = Distance / Time = 1 divided by 1/6 = 6 km per hour
