Question

Excluding the stoppages, the speed of a bus is 64 km/hr and including the stoppages the speed of the bus is 48 km/hr. For how many minutes does the bus stop per hour?

  • 12.5 minutes
  • 15 minutes
  • 10 minutes
  • 18 minutes
  • 21 minutes
Answer- B

Assume distance is 192km as LCM of 64 and 48 is 192

Time taken without stoppage = (192/64) = 3 hours

Time taken with stoppage = (192/48) = 4 hours

Therefore the bus stops for 1hr in every 4 hrs with stoppage journey.

=> Stoppage time per hour = (1/4) hr = 15minutes
