Step-by-step explanation:
3x x 10 = 22
3x x 10 - 10 = 22 - 10
3x = 12
3x ÷ 3 = 12 ÷ 3
x = 4
5x + 8
5(4) + 8
20 + 8
28

Dividing we get,

Adding, we have,

Thus, the total time taken by Joshua is 
To determine the average speed we use the formula,

where
and 
Hence, substituting the values we have,

Dividing, we get,

Thus, the average speed of Joshua during that time is 2500 m/h.
