35. A man made a trip of 480 km in 9 hours. Some part of the trip was covered at 45 km/hr and the
remaining at 60 km/hr. Find the part of the trip covered by him at 60 km/hr.
​

Answer 1

Answer:

Total distance of trip =480km

Total time of journey =9 hrs

Let 'x' hrs be travel with 45 km/h and rest with 60 km/h

15x+60(9−x)=480

45x+450−60x=480

15x=60

[x=4]

Now, Total distance covered with 60 km/hr =60×5=300km.
