Answer:
16.7
Step-by-step explanation:
We can use the Pythagorean theorem, a^2 + b^2 = c^2.
a = 11
c = 20
11^2 + b^2 = 20^2
121 + b^2 = 400
b^2 = 279
b = sqrt(279) = 16.7
 
        
             
        
        
        
Average speed = (total distance) / (total time)
Average speed = (192 km) / (8 hours) = 24 km per hour .
