Scott travels north 2 miles and then goes west 5 miles before coming straight back south 7 miles what is his displacement

Displacement is 5√2 miles

Explanation:

From south, Scott travelled 2 miles north and then 5 miles west then he came back south by 7 miles.

I've attached a diagram to indicate Scott's path travelled

Now, displacement is a vector quantity that tells us the overall change in position by Scott i.e distance from his initial position to his current final position while distance is a scalar quantity and tells us how much ground Scott covered in his motion over the entire trip.

Now, from the attached image, the displacement is denoted by "d".

d can be found from pythagoras theorem.

Thus;

d² = 5² + 5²

d = √50

d = 5√2 miles

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

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
