Answer 2

Answer:

FORMULA FOR SPEED

Explanation:

SPEED= DISTANCE TRAVELLED

                      TIME TAKEN

FOR EXAMPLE: A TRAIN STARTS FROM A STATION. THE DISTANCE FROM THE STATION TO ANOTHER STATION IS 120 KM AND THE TRAIN REACHES ITS DESTINATION IN 3 HOURS. WHAT IS THE SPEED OF TRAIN?

SOLUTION:     SPEED= DISTANCE TRAVELLED

                                                TIME TAKEN

                                    =     120 km

                                              3    hrs       120 divided by 3=40 THEREFORE SPEED  =    40 kph (it is kph because distance is in kilometres and time taken is in hrs)
