*There are 36 steps on the elevator as it took Tom 18 seconds to reach the top of the elevator (when it wasn't working), taking 2 steps per second.(2*18=36).
*When the elevator was fixed Tom moved through it taking 2 steps per second and managed to reach its top in 12 seconds. This means that he had covered 3 steps in the space of a second while he was moving up the elevator (fixed). (36/12=3).
<em>*Knowing this information, we can come to terms with the fact that the elevator can move Tom 1 step upwards per second if he doesn't make any effort to move up the elevator while its working. As there are 36 steps on the elevator, on Wednesday it took Tom 36 seconds to reach its top.</em>
Answer:
24 students per mile
Step-by-step explanation:
Given in the question,
Length of rectangle for building university = 75 miles
Width of rectangle for building university = 25 miles
Total area:
Length x Width
= 75 x 25
= 1875 miles²
Only 70% of the buildings at this university are used for instruction
70% of 1875 miles²
70/100 x 1875
= 1312.5 miles²
32,125 students are enrolled at this university
So,
1312.5 miles² = 32,125 students
1 mile = 32,125/1312.5
= 24 students per mile
