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.

a high speed train travels south for 2.00 h for a distance of 454km. what is its average velocity?
41m/s
The train travels at 123.7 km/h
Assuming no accelerate or decelerate figures, the average speed is 48 MPH.
This is an average speed of 42.54 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
30,000 metres or 30km
540 kilometres per hour.
