Answer. Answer: Speed is 120/3=40 Kmph.
What is the speed of the train that travels 120 km in 2 hours?
What is the average speed of a plane that covers 120 km in one hour and twenty minutes?
Answer: An aeroplane covers a distance of 120 km . time taken in 1 hours 20 minutes . now, speed of a aeroplane = distance of aeroplane / time taken of aeroplane =120km/1 hours 20 minutes = 100 km/h .
What is the speed of the train that travels 120 km in 2 hours Brainly?
Answer: Formula for speed: It’s speed is 48 km/hr.
How do you get the average speed?
Divide the total distance traveled by the total time spent traveling. This will give you your average speed. . So if Ben traveled 50 mph for 3 hours, 60 mph for 2 hours, and 70 mph for 1 hour, his average speed was about 57 mph.
How fast do planes accelerate on the runway?
An average commercial jet accelerates to between 120 and 140 knots prior to liftoff. To do this in 30 to 35 seconds requires a good sustained acceleration. This is something that pilots look for during a takeoff roll.
How do airplanes calculate speed?
In an aircraft the speed is “measured” with a pitot tube. Together with the static pressure one can determine not the speed of the aircraft, but the speed of the air flowing around the aircraft, the airspeed. Thus the speed of the aircraft relative to the airmass it is flying in.
How far can a cyclist travel in 1.5 hours if his average speed is 12 km per hour?
18km far can a cyclist travel in 1.5 hours if his average is 12km/h.
How much time does it take a person to walk 12 km north at a velocity of 6.5 km h?
(12 km) / (6.5 km/hr) = 1.846…
If he’s walking in any other direction, it takes him longer than that. distance, no matter how long he walks.
What is difference between speed and average speed?
Speed can be thought of as the rate at which an object covers distance. … The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero.
What was his average speed in mph over the last 400 m?
Answer: His average speed in mph over the last 400 m is 7.7 m/s.
How Do You Solve average speed problems?
How To Calculate Average Speed
- To get average speed, s , divide total distance by elapsed time: Dt. D t.
- To get elapsed time, t , divide total distance by speed: Ds. D s.
- To get distance, D , multiply speed times the amount of time: s × t.
