To calculate the average speed, we need to know the time it took to drive to Cape Town.
They left at 6am and arrived at 23:20, so the total time of the journey can be calculated as follows:
Time = (23 hours + 20 minutes) - 6 hours
Time = 17 hours + 20 minutes
Time = 17.33 hours (rounded to two decimal places)
Now, we can use the formula:
Average speed = distance / time
Average speed = 1420 km / 17.33 hours
Calculating this, the average speed is approximately 82.01 km/h (rounded to two decimal places).
If the total distance covered to cape town was 1420 km, calculate the average speed (in km /h) at which they drove , correct to two decimal places.
Use formula: average speed = distance × time
*they left 6am and reached their destination at 23:20
