Ashley walks from building I to building II at a constant speed
of 1.3 m/s. It takes her 2 minutes to get to building II from
building 1. What is the distance between the two buildings?

The distance is 156 Meters

Explanation:

It takes 2 minutes or 120 seconds to get from one building to the other, and she is walking at a speed of 1.3 meters per second, therefore if you multiply 1.3*120 you get 156 meters

seeing the graph would

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
