Answer:
The answer to the question is
Shawn has to wait for 3 minutes for Jason to meet him at 2 miles away from the station
Step-by-step explanation:
To solve the question, we note the variables
Bike speed = 20 mph
Start point of Jason = 1 mile away from the station
Starting point of Shawn = 2 mile away from the station
Total miles away from station = y
Direction of biking = away from the station
Therefore if they both start biking at the same time, Shawn is ahead of Jason
Riding speed of Shawn = Riding speed of Jason = 20 mph
That is Shawn has to wait for 1/20 hr or 3 minutes for Jason to meet him at 2 miles away from the station
