Answer:
A. 50 minutes
Step-by-step explanation:
Jan's change in altitude from her base camp to that altitude is ...
1250 -500 = 750 . . . feet
Dividing distance by rate gives time, so we have ...
hiking time = (elevation change)/(rate of change) = (750 ft)/(15 ft/minute)
hiking time = (750/15) minutes = 50 minutes
