Answer:
a). Distance from the surface of miner elevator=532 feet, Distance from the surface of equipment elevator=60 feet
b). The miner elevator is deeper since it is 472 feet deeper than the equipment elevator
Step-by-step explanation:
Equipment elevator speed=4 feet per second
Miner elevator=14 feet per second
Total time of miner elevator=(23+15)=38 seconds
Total time of equipment elevator=15 seconds
a). Distance from the surface of each elevator
Distance from the surface of miner elevator=Miner Speed×Miner Time
Distance=(14×38)=532 feet
Distance from the surface of equipment elevator=Equipment Speed×Equipment Time
Distance=(15×4)=60 feet
b). Which elevator is deeper
Distance from the surface of miner elevator=532 feet
Distance from the surface of equipment elevator= 60 feet
Difference=(532-60)=472 feet
The miner elevator is deeper since it is 472 feet deeper than the equipment elevator
