Neco Model Questions Vol1 2020 Geography Question 41
Practice objective / multiple choice question 41 from the 2020 Neco Model Questions Vol1 Geography examination.
A train travels from A to B covering a total distance of 120 km. The first 20 km are on level track at a speed of \(80\) km/h, the next 30 km are uphill on a gradient of 1 in 100 where the speed reduces by 20\% of the level speed, and the remaining 70 km are downhill on a gradient of 1 in 150 where the speed is \(k\) times the level speed. The train stops for 5 minutes after the uphill section. A bus travels the same 120 km at a constant speed of \(90\) km/h and makes two stops of 4 minutes each. To have the same total travel time as the bus, what percentage increase in the downhill speed relative to the level speed (i.e., \((k-1)\times100\)\%) is required? Give your answer to one decimal place.
