The question is asking for how many minutes it walks. Since it walks 5 meter per minute and walks 62.5 meters, you have to divide 62.5 by 5 to get how many minutes the tortoise walks. 62.5 divide by 5 is 12.5. in minutes, 0.5 is 30 seconds, therefore the tortoise walked for 12 minutes and 30 seconds or 12 1/2 minutes.
Answer:
36 passengers
Step-by-step explanation:
Maria averages 20 passengers every 20 minutes, so she places 1 passenger per minute.
Sal averages 20 passengers every 25 minutes, so he places 0.8 passenger per minute.
If they work together, they can place (1 + 0.8) passengers = 1.8 passengers per minute.
In 20 minutes, they can load
1.8 passengers/minute * 20 minutes = 36 passengers
First, determine the circumference (C) of the circle, the equation,
C = 2πr
Substituting the value or the radius,
C = 2π ( 4) = 8π
The arc length is the product of the circumference and the ratio between the subtended angle and 360. The mathematical expression is already,
S = (8π) x (72 / 360) = 0.8π
Thus, the arc is 0.80π.
