Speed of an object is defined as the distance covered by it in per unit time interval. It is obtained by dividing the distance covered by the object by the time it takes to cover that distance.
Therefore , Speed = Distance covered / Time taken
The speed practice problems can be solved by using the above formula.
Here are some of the speed practice problems:
Speed Problems
Problem: A train crosses a pole in 15 seconds. If the length of the train is 300 meters, find the speed of the train. (Answer: 20 m/ sec).
Solution : Speed = Distance / time
Speed = 300 / 15
Speed = 20 m / sec is the answer.
Practice Problems on Speed.
Problem: Brittany walking at a speed of 20 km/h reaches her college 10 minutes late. Next time she increases her speed by 5 km/h, but finds that she is still late by 4 minutes. What the distance of the college from her house?(Answer: 10 km).
Problem: The average speed of Ryan for a 6 hrs journey is 45 km/h. If he travels with the speed of 40 km/h for the first four hours , find the average speed for the last two hrs.
Problem: X and Y are two stations 600 km apart. A train starts from X and moves towards Y at the rate of 25 km/hr. Another train starts from Y at the rate of 35 km/hr. How from X they will cross each other? (Answer: 250km)
Problem: The boat goes 15 km upstream in 80 minutes. The speed of the stream is 5 km/h. What is the speed of the boat in still water? (Answer: 16.25 km/hr)
Problem: A motorboat whose speed in still water is 15 kmph goes 30 km downstream and coves back in a total 4 hours and 30 minutes. Determine the speed of the stream. (Answer : 5 kmph)
Problem: Alex average speed for the 5 hours is 10 miles per second. His average of the next three hours is 15 miles per hour. Find the average speed for the total 8 hours. (Answer: 11.87 miles per hour).
Therefore , Speed = Distance covered / Time taken
