A tempo, while travelling at 70 kmph, uses 30% more petrol than it uses while travelling at 50 kmph for travelling a certain distance. Using one litre of petrol, it can travel 19.5 km at 50 kmph. How far can the tempo travel on 10 litres of petrol at a speed of 70 kmph?

• 150 kms.
  @50 kmph , one km distance uses 1/19.5 ltr petrol.
  @70kmph, one km dist. uses 1.3/19.5 ltr petrol
  Distance travelled with 10 ltrs @ 70kmph = 10*19.5/1.3= 150 kms.

• 1 ltr 19.5KM
  so
  1.3 ltr 19.5Km
  so
  10 ltr =19.5*10/1.3=150KM

• @50 km/h it uses 1 liter petrol to travel 19.5km.
  then @70 km/h it will use 1.3 liter petrol to travel 19.5 km.
  so it will travel (19.5/1.3)*10 distance in 10 liter petrol.
