Hints:
speed = (distance) / (time)
You need to convert 1 hour + 45 minutes into a single unit, such as hours or minutes.
a high speed train travels south for 2.00 h for a distance of 454km. what is its average velocity?
30,000 metres or 30km
In one minute, it travels about 0.65 miles. In 70 minutes it travels about 45.63 miles.
In general, we will find the average speed of a moving object by dividing the total distance it travels by the total time elapsed in its travel.We can find the actual speed of the object if it moves with a constant speed during all of its travel. But if the object is something like a bus or train that makes stops along the way, we discover its average speed by dividing the total distance it travels by the total time it took to travel that distance.
200km
454 km
a high speed train travels south for 2.00 h for a distance of 454km. what is its average velocity?
The train travels at 123.7 km/h
Average speed = Total Distance/Total Time = 350/3 = 116.66... km per hour.
average speed = S1+S2/2 here s1 = 40kmph s2 = 60kmph Average speed = 40+60/2 100/2 = 50 kmph
distance = rate x times; distance = 226 miles, time = 2 hours and 30 minutes = 2.5 hoursrate = distance/timerate = 226 mi/2.5 hrrate = 90.4 mi/hr
33,055m or 33.055Km
540 kilometres per hour.
30,000 metres or 30km
The average speed of the train for the entire trip would be the harmonic mean of 60 mph and 40 mph. Using the formula for harmonic mean: 2 * 60 * 40 / (60 + 40) = 48 mph. So, the average speed of the train is 48 mph.
In 6 hours @ 120 km per hour, the train travels 120*6 = 720 km. In 5 hours @ 100 km per hour, the train travels 100*5 = 500 km. So, in all the train travels 720 + 500 = 1220 km in 6 + 5 = 11 hours. Its average speed is 1220/11 =110.9090.. recurring km per hour.
In one minute, it travels about 0.65 miles. In 70 minutes it travels about 45.63 miles.
