Ahmad went on a bicycle tour. In the first two hours , he averaged 12 km/h; but in the next three hours he averaged 8 km/h;. A)Calculate the total distance covered b) , calculate his average speed for the whole journey

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

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
