Rex is taking lessons for his driver’s license. He wants to take 40 hour-long lessons before his test, and decides to have two-hour sessions twice a week until he has done his test. After 6 weeks, how many more weeks will Rex need to continue taking lessons to reach his goal?
assistant
How many lessons does Rex take each week? ** Each week, Rex is taking 2 hour-long lessons * 2 times a week = <<2*2=4>>4 lessons.
How many lessons has Rex done after 6 weeks? ** After 6 weeks, he has done 4 lessons per week * 6 weeks = <<4*6=24>>24 lessons.
How many more lessons does Rex need to take? ** So Rex still needs 40 total lessons – 24 lessons taken = <<40-24=16>>16 lessons.
How many more weeks will Rex need to continue taking lessons to reach his goal? ** He will therefore need lessons for another 16 lessons / 4 lessons per week = <<16/4=4>>4 weeks.
