What is the average speed of the car if it traveled 80 km in 2 hours?
The speed is 40km/hr.
(b) Average speed is (80 km)/2 hr) = 40 km/hr. In this case, average speed is apparently equal to average velocity.
How far will you travel if your speed is 80 km/hr for 2 hrs and 30 min?
1 Expert Answer
Distance is rate times time. 30 minutes is 1/2 hour or 0.5 hours. Therefore, distance = 80 x 0.5 = 40 kilometers.
What is the speed of 80 km in 4 hours?
How many hours drive is 80 km?
It will take just 1 hour to travel 80km.
How can speed be calculated?
Which is a unit of speed?
Speed is a measure of how fast something is travelling. The most common units of speed are metres per second (m/s), kilometres per hour (km/h) and miles per hour (mph).
Is 80 kmh fast?
How fast is 80 kilometers per hour? A Thomson’s gazelle can reach speeds of up to 80 kph. In other words, 80 kilometers per hour is 1.11 times the speed of a Greyhound, and the speed of a Greyhound is 0.901 times that amount.
How do you find average speed in km HR?
What is the distance traveled by a car which traveled at a speed of 80 km/hr for 3 hours and 30 minutes?
Distance = Speed x Time = 80 x 7/2 = 280 kms. Therefore, the distance travelled by the car moving at a speed of 80 kmph for 3 hours 30 minutes is 240 kms.
What distance would a car travel in 4 hours at 80 km?
We are given the fact that the “trip takes 4 h at 80 km/h “. So the total distance of the trip is 320 km .
How far does a car travel in 1 minute?
Speed in miles per hour (mph)
Miles per hour is often used for car speeds. One minute at 60 mph will move you 1 mile.
How do you calculate distance traveled?
How do you find speed with only time?
To find out something’s speed (or velocity) after a certain amount of time, you just multiply the acceleration of gravity by the amount of time since it was let go of. So you get: velocity = -9.81 m/s^2 * time, or V = gt.
