Step-by-step explanation:
first, we will calculate the distance both the buses cover in one hour together. then, we will have to divide the total distance to be covered by the total distance covered in one hour.
distance covered in one hour: 50km+60km = 110 km
time taken to cover 440 km = 440/110 hr = 4 hrs
