Question

a car covers 20m in 2second then another 30m in 3second find its average speed

Answer 1

average speed = total distance travelled ÷ total time taken
∴  average speed = 20+30 m ÷ 2+3 sec 
                                 = 50÷5
                                 = 10 m/sec

Answer 2

HEYA ! 



Here's your Answer ↓



GIVEN : 


1) Speed = 20 m              Time = 2 seconds


2) Speed = 30 m              Time = 3 seconds


FIND:


1) Average speed


SOLUTION :



1) Average speed = Total Distance
                                ____________

                                 Total time 


= 20 + 30              50 

________   =   _______   = 10 

 
 2 + 3                   5 




∴ The average speed = 10 m/sec
