answers

Answer

Plane

There are two types of curved mirrors, concave and convex. Both curved mirrors form that are magnified.

Concave will form an image on the same side as the object and it may not be the mirror used.

Plane mirror on the other hand forms images behind the mirror in all cases. The image formed is upright meaning it is virtual.

∴ The mirror used is a plane mirror.

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
