Analysis
To determine how far apart the two cyclists
are after 30 seconds, we can calculate the distance each cyclist travels and
then find the difference between those distances.
Calculate the distance traveled by each
cyclist:
Cyclist A:
DistanceA=SpeedA× Time = 12m/s × 30s = 360m
Cyclist B:
DistanceB= SpeedB
