Question 1
Two cars, A and B, start to move towards each other. If they meet when A has travelled $(1/5)$th of the distance, what is the ratio of the speed of B to the speed of A?
Question 2
Two cars A and B begin to move towards each other and meet midway after travelling equal distance. What is the initial distance between them if the speeds of A and B are 2 km/h and 8 km/h, and B started 1 hour late?
Question 3
A vehicle travels 50% of its distance at 5 km/h, and the remaining 50% at 11 km/h. What is the total distance, if it travelled for a total duration of 32 hours?
Question 4
Speeds of A and B are in the ratio 17 : 11. What is the speed of A if B can cover a distance of 55 Km in 1 hour?
Question 5
A train passes two persons walking in the same direction as the train. The time it takes to move past the man running at 13km/h is 19sec, whereas the time it takes to cross the other man running at 26km/h is 20sec. What is the speed of the train?
273km/h.
274km/h.
272km/h.
275km/h.
Ans: a
Let the speed of the train be v km/h. Length of the train calculated with the data for the first man = $(v - 13) × 19$. It should equal the length obtained from the data for the second man. So $(v - 13) × 19$ = $(v - 26) × 20$. Please note that we have not converted seconds to hours because that factor will ultimately cancel away. Solving for v we get 273km/h.
