A train takes 2 hours and 30 minutes to travel between 2 cities that are 210 km apart. What was the average speed of the train?
Could someone take me through the steps please on how to get the answer
avg velocity=distance/time
is that supposed to be d=vt?
No. The definition of average speed is distance traveled divided by time.
oh wait no it's asking me for average speed
As bobpursley stated:
"The definition of average speed is distance traveled divided by time."
i know how to do this ...i was just lookiing at the wrong page :P sorry
To find the average speed of the train, you need to divide the total distance traveled by the total time taken.
Step 1: Convert the time from hours and minutes to decimal format.
In this case, the train takes 2 hours and 30 minutes, which is equivalent to 2.5 hours. To convert minutes to decimal format, divide the number of minutes by 60. Thus, 30 minutes divided by 60 minutes per hour equals 0.5 hours.
So, the total time taken by the train is 2.5 hours.
Step 2: Divide the total distance traveled by the total time taken.
The train travels a distance of 210 km.
Now, divide the distance (in kilometers) by the time (in hours):
Average speed = Distance / Time
Average speed = 210 km / 2.5 hours
Step 3: Calculate the average speed.
Divide 210 km by 2.5 hours:
Average speed = 84 km/h
Therefore, the average speed of the train is 84 km/h.
