A Mumbai local train moves at a steady speed. The double number line matches distance with time. What number goes in place of the orange ?

Question

Accepted Answer

30. 9 km in 12 minutes means 3 km every 4 minutes ( 9 : 12 = 3 : 4 ). 40 = 4 × 10 , so distance = 3 × 10 = 30 km. (27 just adds another 9; but 40 min is not 12 more than 24.)
