On a 100km track, a train travels the first 30 km at a uniform speed of ` 30 kmh^(-1)`. How fast must the train travel the next 70 km so as to averge the next `40km h^(-1) for entire trip.

On a 120km road, a car travels the first 30km with at a uniform speed of 30km/h. How fast must the car travel for the rest of track so as to have an average speed of 60km/h for the entire journey?

A train is moving at a uniform speed of 75 km/hour : How far will it travel in 20 minutes?

A car travels 30 km at a uniform speed of 40 km/h and the next 30 km at a uniform speed of 20 km/h . Find its average speed.

A car travels 4 km in 3 minutes. Find the speed of car in cms^-1

A man walks at a speed of 6 km h^-1 for 1 km and 8 km h^-1 for the next 1 km.What is the average speed for the walk fo 2 km?

A car is moving at a uniform speed of 80 km/hr . (i) How far will it travel in 12 minutes ? (ii) How much time will it take to cover a distance of 240 km

A train travels 360 km at a uniform speed. If the speed had been 5 km/h more, it would have taken 1 hour less for the same journey. Find the speed of the train.

A train travels at a speed of 60 km/h for 0.52 h, at 30 km/h for the next 0.24 h and then at 70 km/h for the next 0.71 h. What is the average speed of the train ?

A car travels a distance from A to B at a speed of 60 km h^-1 and returns to A at a speed of 30 km h^-1 . The average speed of the car for the whole journey is:

Represent the following situations in the form of quadratic equations: A train travels a distance of 480 km at a uniform speed. If the speed had been 8km/h less, then it would have taken 3 hours more to cover the same distance. We need to find the speed of the train.
