Question

I went from my house to playground 300meters away in 10 minutes .I ran back and reached in 2minutes.what was my average speed ?

Answer 1

distance is equal to 300m,time is equal to 10 minutes which is equal to 600 seconds.
Then speed.....

S=D÷T
S=300/600 m/s. (leave it as it is)

now
2minutes =120 secs

So,
distance is equal to 300 meters and time is equal to 2m which is is equal to 120 seconds

so the speed will be 300÷120 which is is equal to 5÷2m/s

5/2=2.5 m/s which is ur ans...

hope it will help u a lot..........

Answer 2

total d is 600 m

total t is 12m

600/12*60

is 5/6 m/s
