Find the ratio of the time taken to cover two distances in the ratio 4 : 5 at speeds in the ratio 4 : 3 respectively. Q 2. From home to office, if I travel at 3/5 of my usual speed, I am late by 12 minutes. Find the time that I take usually and the time taken at the reduced speed. Q3. Over a certain distance, if the speed had been 10% more, by how much percent less would the time taken be? Q4. If a man walks at the rate of 5 kmph, he misses a train by 7 minutes. However, if he walks at the rate of 6 kmph, he reaches the station 5 minutes before the departure of the train. Find the distance to the station. Q5. At its usual speed of 40 kmph, the bus covers its journey on schedule. But when its speed reduces to 35 kmph, it takes 15 more minutes than scheduled time. Find the distance of the journey. Q6. A car covers a distance in 8 hours. Had the speed been increased by 4 kmph, the time taken would have reduced by 30 minutes. Find the distance. Q7. A is twice as fast as B and B is thrice as fast as C. If B takes 18 minutes to cover a certain distance, find the difference in the time taken by A and C to cover the same distance. Q8. A train meets with an accident and travels at 4/7 of its regular speed hereafter and hence it reaches its destination 36 minutes late. Had the accident occurred 30 kms further, the train would have been late by only 21 minutes. Find the regular speed of the train.
