A horse traveled at a constant speed of 30 km/h for the initial 2 hours and then at a constant speed of 20 km/h for 3 hours. What was its average speed?


Answer:

24 km/h

Step by Step Explanation:
  1. Given, speed for the initial 2 hours =30 km/h
    Speed for the remaining 3 hours =20 km/h
    So, the total time of the journey =2+3=5 hours
    Average speed can be found by using the formula below:
    Average speed = Total distance ÷ Total time
  2. Distance covered in the initial 2 hours =2×30
    =60 km.
    Distance covered in the remaining 3 hours =3×20
    =60 km.    
    Total distance covered =60+60
    =120 km.
  3. Average speed =120÷5
    =24 km/h.
  4. Hence, the average speed of the horse was 24 km/h.
