Let us understand this by an example. A car travels a distance of 100 km in 2 h. Its average speed is 50 km h–1. The car might not have travelled at 50 km h–1 all the time. Sometimes it might have travelled faster and sometimes slower than this. Example 8.1 An object travels 16 m in 4 s and then another 16 m in 2 s. What is the average ...
2 dni temu · Speed Distance Time Word Problems With Solutions. Q1. A train is travelling at a speed of 160 km/hour. It takes 15 hours to cover the distance from city A to city B. Find the distance between the two cities. Solution: Speed= 160 km/hr. Time= 15 hours. Using the formula, $\text{distance=speed }\!\!\times\!\!\text{ time}$ Distance= $160\times 15 ...
Which one of them is moving the slowest of all? The distance moved by objects in a given interval of time can help us to decide which one is faster or slower. For example, imagine that you have gone to see off your friend at the bus stand. Suppose you start pedalling your bicycle at the same time as the bus begins to move.
18. Given below as Figure 13.8 is the distance-time graph of the motion an object. Fig. 13.8 (i) What will be the position of the object at 20s? (ii) What will be the distance travelled by the object in 12s? (iii) What is the average speed of the object? 19. Distance between Bholu’s and Golu’s house is 9 km. Bholu
4 gru 2023 · The speed of an object is the distance travelled divided by the time taken to cover that distance. Its basic unit is metre per second (m/s). The motion of objects can be presented in pictorial form by their distance-time graphs.
NCERT Solutions for Class 7 Science Chapter 13 Motion and Time 4. The distance between two stations is 240 km. A train takes 4 hours to cover this distance. Calculate the speed of the train. Solution: Distance between two stations = 240 kms Total time take = 4 hrs/240 minutes = 60 km/h 5.
This document contains 13 questions about classifying types of motion, speed, distance, and time calculations. It provides examples of straight line, circular, and oscillatory motion. It also discusses speed calculations using distance and time values.
