What is the speed of a person in kilometers per hour if the distance he travels is 39 kilometers in 2 hours?
We will use the concept of speed, distance, and time to find the speed of the person.
Answer: The speed of the person is 19.5 kilometers per hour.
Let's see how we will use the concept of the speed formula to answer this question.

Distance = 39 kilometers
Time = 2 hours
Speed = (39 / 2) km/hr
