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
- 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 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. Average speed =120÷5 =24 km/h. - Hence, the average speed of the horse was 24 km/h.
