Answer:
B. 75 stories
Step-by-step explanation:
1.5 minutes is equal to 90 seconds.
To get how many times the elevator will rise in 90 seconds, we divide it by how many seconds it takes to rise.
90/6 = 15
It will rise 15 times in 90 seconds. Since it rises 5 stories each time, we multiply 15 by 5.
15 x 5 = 75
