## 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.
