Shweta rides at the rate of 10 km per hour but stops for 10 minutes to take rest at the end of every 15 km. How many hours will she take to cover 100 km

• 11 hours
  because after every 15 km she will take a rest of 10 minutes so after every 90 minutes she will 10 min break.
  she will 10 hours to cover 90 km distance and 1 hour to cover remaining 10km.
  so the answer is 11 hours.

  v=10km/h
  15km time 1(1/2)
  rides time =6*1(1/2)+1=10
  15 30 45 60 75 90 100
  6time rest =6*10=60
  total time=11 hour

• 11hours
  for every 15 km she takes 100minutes
  and as 15*6 =90 i.e for 90kms she takes 600minutes now for 10 km she takes 60 minutes
  total=660minutes= 11hrs

• for the first 15 km she will stop for 10 min so time taken for 1st 15=15/10+10/60hr=5/3
  so in 100 km she will stop 6 times for 15 km an d remaining 10 km is left 100/15
  so 6*5/3+10/10=11hrs

• take breaks after 15 km , to cover 100 km she took breaks for 6 time for 10 min
  total break time = 6 * 10 = 60 min = 1 hr
  speed = 10 km/hr
  time = 100 / 10 = 10
  total time taken = time + total break time = 10 + 1 = 11 hrs
  she will require 11 hrs to cover 100 km distance

• 10 hours and 50 min
  she covers 100 km with a speed of 10 km/h
  so time taken is 10 h
  and at each 15 km she will rest for 10 min so 15..30..45..60..75..90 total 5 times she will rest means 50 min

• (100/10)+int(100/15)*10= 11 hours
• 8 years agoHelpfull: Yes(0) No(0)
• for every 15km ,time taken=time taken for 10km+time taken for 5km+rest time=60+30+10 mins
  so 15*6+10km=100*6+60 mins=660mins=11 hours.

• she wil take 11 hours...
  for every 15 km she takes 100 min...
  so,
  for 30km, she vl take 200 min
  so on..
  for 90 km she take 600 min...
  for next 10 km she will take 60 min..
  therefore total time taken = 660 min.. which is 11 hours

• Total no of rests=5
  Time of rest=50 min
  Total no of trip of 15 km=6+ some portion of 7th(I.e 10km)
  So total time=1.5*6hr+50 min+1hr=10 hr+50 min...

• 11hrs
  every 2hrs covers 15km
  so 10hrs covers 90km
  remining 10km in 1hr
  So total time 11hrs

• ride rate is 10 km/h
  for 100 km its will take time as 100/15=6.abcd
  so it will take rest in hole journey is 6*10=60 and to travel 100 km as per rate 10 km/h its will take 10 hours
  so finally shweta takes 10+1=11 hours to complete the journey.
