Speed increases if you cover more distance in the same amount of time, or if you cover a distance in less time. Distance can be calculated if you know the speed and time, with the formula: distance = speed × time. Time required to cover a distance can be found if you know the speed and distance, using the formula: time =. distance. speed.
A cyclist travels at an average speed of 18 km/h for 4 hours. Work out the total distance cycled. Draw the formula triangle. Working clockwise from the top, enter D (distance), T (time) and S (speed).

Several units of speed are possible. They depend on the units used to measure distance and time. Some examples: 1. Car: 80 miles/hour 2. Ship: 20 nautical miles/hour 3. Rocket: 500 miles/minute 4. Train: 100 kilometers/hour 5. Athlete: 8 meters/second It is possible to convert one unit to another. Let us see some examples.
We can use the speed formula to calculate distance and time also. However, before applying it, we have to make sure that units of the known quantities are consistent.
While going from one point to another, an object may travel at different speeds. Its average speed is the ratio of total distance and total time elapsed during the journey. AverageSpeed=TotalTimeTotalDistance Let us understand with an example.
These questions cover speed and unit conversion concepts discussed above. Some of these are challenging. All the best!
Oct 15, 2018 · The unit of time in speed should be the same as that of the given time. Solved examples to calculate distance when speed and time are given: 1. How much distance will be covered in 5 hrs at a speed of 55 km per hour? Solution: Distance covered in 1 hour = 55 km. We know, Distance = Speed × Time. Distance covered in 5 hrs = 55 × 5. = 275 km.
The figure above shows the speed time graph ( t , v ) of a train travelling along a straight horizontal track between two stations which are 6.3 km apart. The train starts from rest at the first station and accelerates uniformly for 360 m, reaching a speed of 36 ms− decelerates uniformly at 1.2 ms−.
We can now input the speed (39.44 m/s) and the time (2580 s) into the calculator to show that the train travelled a distance of 101,755 metres. The equation for distance is: Where: d = distance (m)s = speed (m/s or ms-1) t = time (s) To calculate distance enter a speed in metres per second (m/s) and a time in seconds (s) then click Calculate ...
Distance, rate and time problems are a standard application of linear equations. When solving these problems, use the relationship rate (speed or velocity) times time equals distance. r⋅t = d r ⋅ t = d. For example, suppose a person were to travel 30 km/h for 4 h. To find the total distance, multiply rate times time or (30km/h) (4h) = 120 km.
