A 60-kg hiker wishes to climb a hill 1200 meters high. If he can generate a sustained average power of 500 Watts (realistic!), how long will it take him to climb the hill?.

i need the answer to this too but idk it ; -;

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
