Answer:
Average speed = 24 km/h
Explanation:
- Let the distance be x.
<u>Given the following data;</u>
Uniform speed A = 30 km/h
Uniform speed B = 20 km/h
To find the average speed;
Mathematically, the average speed of an object is given by the formula;
..... equation 1
Total time = TA + TB
Total distance = x + x
Total distance = 2x
Substituting the values into equation 1;
<em>Average speed = 24 km/h</em>
