A trailer driver left Miami at 15:45 and arrived at his destination 637.5 km away at 02:15 the next day.
a. How long did the jpurney take?
b. What was his average speed in km/h
c. What was his average speed in ms^-1
To answer these questions, we need to calculate the time and average speed of the journey.
a. To calculate the duration of the journey, we need to find the time difference between the departure and arrival.
First, let's convert the departure time from 12-hour to 24-hour format:
15:45 is equivalent to 15 + 12 = 27 hours + 45 minutes = 27.75 hours.
Now, let's convert the arrival time to 24-hour format:
02:15 the next day is equivalent to 2 + 24 = 26 hours + 15 minutes = 26.25 hours.
To find the duration, we subtract the departure time from the arrival time:
26.25 hours - 27.75 hours = -1.5 hours.
Since the answer is -1.5 hours, it means he arrived 1.5 hours before he departed. This could be due to crossing time zones or an error in the time given. Please clarify the time given for the arrival.
b. To calculate the average speed in km/h, we need to divide the distance traveled by the time taken.
Average speed (km/h) = Distance (km) / Time (h)
However, since there is uncertainty in the time, we cannot accurately calculate the average speed in this case.
c. Similarly, since we don't have an accurate time measurement, we cannot calculate the average speed in meters per second (m/s).
