英语翻译 the average speed of a car is given by the formula S=D/T,where D is the distance covered in kilometers and T is the time taken in hours,Find: 1.the speed,if 800 km is covered in 10 hours. 2.the speed of a car which takes 4.5 hours to travel a distance of 250km, ...
Answer: The average speed of the train is 92.86 miles/hour.Example 3: A car travels at a speed of 45 km/hr for 5 hours and then decides to slow down to 40 km/hr for the next 2 hours. Calculate the average speed using the average speed formula....
The formula of the above is S = D/T if “S” is considered “speed,”“D” is taken as “distance,” and “T” is interpreted as “time.” In other words, total distance / total time = Average Speed. What is Average Speed? The average speed of an object can be defined as the...
As you can see, to work out your speed in km/h or mph just apply the speed formula with the relevant units for distance and time. This is how to calculate average speed of a car, bike, boat, or any other vehicle or object.
