If a heavy-load trailer travelled 7 km in 1 hour and 10 minutes, what was its speed in km per hour?

• 6km/hr ans.
  sol:-
  total distance=7km
  total time=1 hour and 10 minutes=70minutes=70/60 hrs=7/6hrs
  from distance formula,
  Average speed=total distance/total time=7*6/7km/hr=6km/hr ans.

• It is 6km/hr
  
  distance=7km time=1 hr 10 min i.e 7/6 hrs
  we knw that speed=dist/time
  =7/(7/6)
  =6km/hr

• First we calculate the speed per minute
  1 hour = 60 minutes
  1 hour and 10 minutes = 60 + 10 = 70 minutes
  7 km travelled in 70 minutes
  travelled in 1 minute = 7 ÷ 70 = 0.1
  speed in km per hour = 0.1 x 60 = 6
  
  The answer is 6 km per hour

• approx 11.42minutes per km
  
  7km = 80minutes (since, 1hour and 10mintes = 80mintutes)
  1km = 80/7
  1km = 11.428571minutes

• in 1 hr 10 min it moves = 7km
  
  in 70 min = 7000 met
  1 min = 100 met
  60 min = 6000 met
  1 hr = 6 km
  
  speed is 6 kmph.

• d=7km
  t=70/60hr
  s=d/t=7*6/7=6km/hr

• Approx 11.42 km per hour.
  
  7km = 80minutes
  1km = 80/7
  1km = 11.428571
