Simpson drives his car with an average velocity of 12 m/s to the east. How long will it him to drive 1440m on a straight road in seconds?

1440÷12=120

Explanation:

because u have to divide the mitre with the 12 m

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
