A cheerleading team is preparing a dance program for a competition. The program must last 4 minutes with an absolute deviation of 5 seconds. Find the least and greatest possible times (in seconds) that the program can last.

Solution

the least possible time the program can last = 3 minute 55 seconds ( without any deviation )

for greatest possible time the program can last = 4 minites + 5 sec of deviation = 4 min 5 sec
