Bill put his french fries in the oven after it finished heating.  The recommended time was 5 minutes for them to be fully cooked.  He put them in for 45 seconds.  How many seconds remained?

### Response:
 5 นาทีคือ 5 x 60 = <<5*60=300>>300 วินาที
เวลาที่ผ่านไปแล้วคือ 45 วินาที ดังนั้น 300-45 = <<300-45=255>>255 วินาทีเหลืออยู่
