Common-Core Grade 7 - 7 Calculating velocity distance and time ii
|
1(kilometer/hour) = 1000(meters) / 3600(seconds) = 5/18 (meters/second), which is its simplified form. To convert km/h to m/s, directly multiply the given value of speed by the fraction 5/18.
Average Speed =Total Distance Travelled/Total Time Taken
Use total distance and total time to find out the avarage speed.
Distance is speed times time.
Total distance travelled divided by time take to get required answer.
Recall how to calculate distance of the train
Speed = distance/time, How to calculate total distance
While converting decimal hours into minutes, these are to be multiplied with 60 and not by hundred.
As both are moving in the same direction, so relative speed = speed of train - speed of loading truck, Distanced traveled= relative speed × time taken
Velocity is distance coved per unit of time.
