Answer:
The plane fall behind 30 seconds every fifteen minutes
Step-by-step explanation:
If the plane was 16 minutes late, so the correct time of arrival was 8 PM
First we have to calculate how many periods of 15 minutes we have in the whole flight.
x= t₂-t₁
t₁=noon=12 hs
t₂=8PM= 20hr
So,
x= 20- 12=8 hours
We have 4 periods of 15 minutes every hour, so the total number of periods is the 8 hours of flight multiplied by 4
T=8*4= 32
Then we have to know how many seconds the fligth was late. That will be
16 minutes multiplied by 60 seconds by minute.
z= 16 *60= 960
We reach the final answer dividing all the seconds that the flight was late (z) by the number of periods (T)
y= z/T=960/32
y= 30 seconds
