A horse traveled at a constant speed of 30 km/h30 km/h for the initial 22 hours and then at a constant speed of 20 km/h20 km/h for 33 hours. What was its average speed?
Answer:
24 km/h24 km/h
- Given, speed for the initial 22 hours =30 km/h=30 km/h
Speed for the remaining 33 hours =20 km/h=20 km/h
So, the total time of the journey =2+3=5=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 22 hours =2×30=2×30 =60 km.=60 km. Distance covered in the remaining 33 hours =3×20=3×20 =60 km. =60 km. Total distance covered =60+60=60+60 =120 km.=120 km. Average speed =120÷5=120÷5 =24 km/h.=24 km/h. - Hence, the average speed of the horse was 24 km/h24 km/h.
