Question

A bus is 320 m ahead of a car and 240 m ahead of a bike. Speed of the bus is 12 m/s and time taken by car to cross the bus is equal to that time taken by bike to cross the bus. If ratio of speed of car to that of bike is 10: 9, then in what time the car will cross the bike?​

Answer 1

Answer:

A bus covers a distance of 240 km at a uniform speed. Due to heavy rain its speed gets reduced by 10 km/h and as such it takes two hrs longer to cover the total distance. Assuming the uniform speed to be x km/h, form an equation and solve it to evaluate the value of x (in km/hr)
