A car travels a distance of 360 kilometre in 5 hours. Find it's speed ...
Speed Calculation
To calculate the speed of a car, we need to know the distance it travels and the time it takes to travel that distance. The formula for speed is:
Speed = Distance/Time
Car 1:
Given that a car travels a distance of 360 kilometres in 5 hours, we can calculate its speed as follows:
Speed = 360 km/5 hours
Speed = 72 km/hour
However, the question asks for the speed in m/s. To convert km/h to m/s, we need to multiply by 1000/3600:
Speed = 72 km/hour * 1000/3600
Speed = 20 m/s
Therefore, the speed of the first car is 20 m/s.
Car 2:
Given that another car travels a distance of 45000 metres in 45 minutes, we can calculate its speed as follows:
Speed = 45000 metres/45 minutes
Speed = 1000 metres/minute
Again, the question asks for the speed in km/h. To convert m/min to km/h, we need to multiply by 60/1000:
Speed = 1000 metres/minute * 60/1000
Speed = 60 km/hour
Therefore, the speed of the second car is 60 km/hour.
