It will take 4.5 hours to travel 432 kilometers at an average speed of 96 kilometers per hour.
Given: Speed = 96 km/h and distance = 432 km
To find: time is taken to cover the distance
Solution:
In ordinary use and kinematics, the speed of an item is the size of the pace of progress of its situation with time or the greatness of the difference in its position per unit of time; it is consequently a scalar amount.
To work out what the units are for speed, you want to know the units for distance and time. In this model, distance is in kilometers (km) and time is in hours (h), so the units will be in kilometers per hour (km/h).
Speed = Distance / Time
=> Time = Distance / Speed
=> Time = 432 / 96
=> Time = 4.5 hours
Therefore, the required time is 4.5 hours.
