How do you calculate average speed with 2 speeds?
Add the two speeds together. Then, divide the sum by two. This will give you the average speed for the entire trip. So, if Ben traveled 40 mph for 2 hours, then 60 mph for another 2 hours, his average speed is 50 mph.
How do u calculate average speed?
The general speed average formula for an object is given as [Average Speed = Total Distance Traveled ÷ Total Time Taken]. SI unit of average speed is m/s.
What is the average speed of 120 km in 2 hours?
=48 km/hr.
What is the average speed of 100 miles in 2 hours?
50 mile/h
Average Speed =50 mile/h.
How do you find average speed in km HR?
Average Speed = (Total distance)/(Total Time) = (1800 + 1800)/(30 + 45) = 3600/75 = 48 km/hr. Hence the correct option here is C) 48 km/hr. So to find the average speed never use the formula of the averages but try to find the total distance covered and the total time taken.
What is the average speed of a plane that covers 120 km in one hour and twenty minutes?
Average speed = 90 km/h.
What must be the average speed in order to travel 130 km in 2.5 hours?
The information given only indicates that 130 km is covered in 2 hours. The average speed would be the distance covered divided by the time. In this case, (130 km)/(2 hours) = 65 km/hour.
What is the average speed of a car?
While the most economical driving speed changes with every vehicle, the general consensus is that it is around 50 mph (80 km/h).
How do you find the average of 3 speeds?
The average speed= 2x30x70/(30+70)= 42 km per hour. Now, this question is not different than the previous question. The only difference is that here the person is traveling 3 equal distance each at different speeds. In this is also, the average speed would be the harmonic mean of all the three speeds given.
How do you find average speed with only speed?
We can write: Time = Distance / speed = 1800/40 = 45 hours. Thus we can find the average speed as: Average Speed = (Total distance)/(Total Time) = (1800 + 1800)/(30 + 45) = 3600/75 = 48 km/hr.
