A car covers distance 440 km in 8 hours. A motorbike covers the same distance in 5 hours. What is the respective ratio between the speed of the car and the motorbike?
Ràtio is.( 440/8.) / (440/5) = 5/8
The ratio between the speeds of two trains is 7 : 8. If the second train runs 400 km in 4 hours, then what is the speed of the first train ?
The speed of the train is two more than twice of the time taken to cover 1012 km at uniform speed. What is the ratio of the values of time taken to cover the distance and speed of the train?
If the ratio of the speed of a boat in downstream and the speed of the stream is 10:1. If the boat can travel 320 km upstream in 20 hours then find the total distance travelled (in km) by the boat in still water in the same time?
