Question

If the total distance covered to Cape Town was 1420 kilometers calculate the average speed in kilometers per hour at which they drove, correct to TWO decimals places
Time taken 14 hours and 20 minutes
Average speed=

Answer 1

To calculate the average speed in kilometers per hour, divide the total distance covered by the time taken.

Time taken in hours = 14 hours + (20 minutes / 60) hours
= 14 hours + (1/3) hours
= 14.33 hours

Average speed = Total distance / Time taken
= 1420 kilometers / 14.33 hours
≈ 99.13 kilometers per hour

Therefore, the average speed at which they drove was approximately 99.13 kilometers per hour.
