Speed Distance And Time Quiz

The cyclist is traveling at a speed of 25km/h. This is determined by dividing the total distance traveled, 125km, by the total time taken, 5 hours. The resulting value is 25km/h, indicating the speed at which the cyclist is moving.

The runner is traveling at a speed of 8.33m/s because 100m divided by 12s equals 8.33m/s.

The snail is crawling at a speed of 0.35cm/s for 45 seconds. To find the distance traveled, we multiply the speed by the time, which gives us 0.35cm/s * 45s = 15.75cm. Therefore, the snail travels a distance of 15.75cm.

The journey from Manster to Lendemon is 186km and the train travels at a speed of 140km/h. To find the time it takes for the journey, we can divide the distance by the speed. Therefore, the journey will take approximately 1.32 hours (186km / 140km/h = 1.32hrs).

The gradient on a distance-time graph represents speed. The gradient is the slope of the line on the graph, which is calculated by dividing the change in distance by the change in time. Speed is defined as the rate at which an object covers distance, and it is calculated by dividing the distance traveled by the time taken. Therefore, the gradient on a distance-time graph represents the speed of an object.

The sprinter runs at a speed of 8.6 meters per second. To find the time taken to complete the race, we divide the distance (200 meters) by the speed. 200/8.6 = 23.3. Therefore, it takes the sprinter 23.3 seconds to complete the race.

On a Distance-Time graph, a curved line that is getting steeper indicates that the object is covering more distance in less time, meaning its speed is increasing. This is a sign of acceleration. Deceleration would cause the line to curve downwards, constant speed is represented by a straight line, a stationary object by a flat horizontal line, and kinetic energy is not directly depicted on a Distance-Time graph. Therefore, the correct answer is acceleration.

The plane travels at a speed of 600km/h. To find the distance it will travel in 3 hours and 30 minutes, we need to convert the time to hours. 30 minutes is equal to 0.5 hours. So, the total time is 3 + 0.5 = 3.5 hours. To find the distance, we multiply the speed by the time: 600km/h * 3.5 hours = 2100km. Therefore, the correct answer is 2100km.

A straight sloping line on a distance-time graph indicates constant speed. This means that the object is moving at a consistent rate without speeding up, slowing down, going uphill, or going downhill. The slope of the line represents the speed, and if the slope is constant, it indicates that the object is maintaining a steady speed throughout the given time period.

Velocity is defined as the speed of an object in a particular direction. It not only considers the magnitude of the speed but also the direction in which the object is moving. This is different from speed, which only measures the magnitude of the object's motion without considering the direction. Therefore, the correct answer is "Speed in a particular direction".
