A train covers a distance of 90 km at a uniform speed. Had the speed be 15 km/ hour more, it would have taken half an hour less for the journey. Find the original speed of the train.

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.

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.

A train covered a certain distance at a uniform speed. If the train would have been 10 km/h faster, it would have taken 2 hours less than the scheduled time. And, if the train were slower by 10 km/h, it would have taken 3 hours more than the scheduled time. Find the distance covered by the train.

After covering a distance of 30 km with a uniform speed there is some defect in a train engine and, therefore, its speed is reduced to 4/5 of its original speed. Consequently, the train reaches its destination late by 45 minutes. Had it happened after covering 18 kilometres more, the train would have reached 9 minutes earlier. Find the speed of the train and the distance of journey.

A man walks a certain distance at a certain speed. Had he walked 1/2 km/hrfaster, he would have, taken 1 hour less. But if he had gone 1 km/hr slower, he would have taken 3 hours more. Find the distance.

Find the time required to cover a distance of 250 km at a speed of 20km per hour.

A bus travels a distance of 120km with a speed of 40km/h and returns with a speed of 30km/h .Calculate the average speed for the entire journey.
