Answer: See explanation
Step-by-step explanation:
We are informed that Ahmad averaged 12 km/h in the first 2 hours. Total distance for the first 2 hours = 12km × 2 = 24km.
In the next three hours he averaged 8 km/h. The total distance for the next 3 hours = 8km × 3 = 24 km
A) Calculate the total distance covered.
This will be the distance covered for the 5 hours. This will be:
= 24km + 24km
B. Calculate his average speed for the whole journey.
This will be:
= Total distance covered / Total time taken
= 48km / 5
= 9.6 km/hour
