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.
The formula of speed is Speed = Distance / Time
Distance = 39 kilometers
Time = 2 hours
Speed = (39 / 2) km/hr
= 19.5 kilometers per hour
Hence, the speed of the person is 19.5 kilometers per hour.
