QUESTION

car travels at a speed of 40 km per hour for 2 hour and then 60 km per hour for 3 hours what is the average speed for the car driving the entire journey..

ANSWER

Average Speed is Total Distance divided by Total Time.

Average Speed is Total Distance divided by Total Time.Total Distance = (40km/hr x 2hr) + (60km/hr x 3hr) = 80km + 180km = 260km

Average Speed is Total Distance divided by Total Time.Total Distance = (40km/hr x 2hr) + (60km/hr x 3hr) = 80km + 180km = 260kmTotal Time = 2hrs + 3hr = 5hr

Average Speed is Total Distance divided by Total Time.Total Distance = (40km/hr x 2hr) + (60km/hr x 3hr) = 80km + 180km = 260kmTotal Time = 2hrs + 3hr = 5hrAverage Speed = Total Distance / Total Time = 260km / 5hr = 52km/hr
