Answer:
20 seconds
Step-by-step explanation:
The distance to cover between the lead skater and trailing skater is 40 meters
The lead skater's rate is 12 m/s
The trailing one's rate is 14 m/s
So, we can say:
second skater is accelerating, or covering up the distance, in 14 - 12 = 2 m/s
So, at a rate of 2 meters per second, how long would it take to cover 40 meters??
We use the distance formula, substitute the known and solve for unknown.
Distance Formula = D = RT
Where
D is distance
R is speed/rate
T is time
We know
r = 2 m/s
d = 40 m
t = ?
Now,
D = RT
40 = 2t
t = 40/2
t = 20 (seconds)
Hence,
it will take 20 seconds for the second skater to catch up (pass)
