Question

the distance between station a and station b is 4.8 miles. the distance between station b and station c is 16 miles. a train takes 4 minutes to travel from station a to station b and another 12 minutes to travel from station b to station c. find the average speed of the train for the whole journey from station a to station c in mph.

Answer 1

The average speed of the train for the whole journey from station A to station C is 77 mph.

Step-by-step explanation:

To find the average speed of the train for the whole journey from station A to station C, we need to calculate the total distance traveled and the total time taken.

The train travels 4.8 miles from station A to station B in 4 minutes, and then it travels 16 miles from station B to station C in 12 minutes.

The total distance traveled is

4.8 miles + 16 miles = 20.8 miles.

The total time taken is

4 minutes + 12 minutes = 16 minutes.

To convert the time to hours, we divide by 60. So, the total time taken is 16 minutes / 60 = 0.27 hours.

The average speed of the train is calculated by dividing the total distance traveled by the total time taken:

20.8 miles / 0.27 hours = 77 mph.
