Directions: Read the following information to answer the question.
D = s × t
A.T.S. 500 × t + 700 × t = 4200
∴ t = 3.5 minutes

The petrol consumption rate of a new car ‘Palto’ depends on its speed and may be described by the graph below:
At 40 km/hr, she spends 200/40 = 5 hrs and thereby consumes
5 × 2.4 = 12.0 litres.
At 80 km/hr she spends 200/80 = 2.5 litres and consumes
Directions: Read the following information to answer the question.
Distance travelled = A : x, B : x – 12, C : x – 18.
When B goes x, C goes (x 18)/(x 12) × x = x – 8. Solve x for runner.
