A car traveling with constant speed travels 150 km in 7200 s. What is the speed of the car?(SI unit system)
Concepts and reason
The main concepts used to solve the problem are speed and distance travelled.
Initially, calculate the speed by dividing the values of distance and time. Finally, use the relation between the units to convert the value to SI unit system.
Fundamentals
The speed of a moving object is the ratio of total distance covered and total time taken that is,
Answer:
The speed is defined as the distance divided by the time taken.
Speed is in general represented with v, distance is represented with d, and the time is with t.
The expression for the speed of the object is,
The speed of the car in SI unit system is 20.83 m/s.
The unit of distance travelled is converted from km to m by using the conversion factors.
The relation between the units Km and m is,
1 Km = 1000 m
