### Instruction:
 Bill aliweka chipsi zake kwenye jiko baada ya jiko kukamilisha kupashwa moto. Wakati uliopendekezwa ulikuwa dakika 5 ili ziive kabisa. Aliweka kwa sekunde 45. Sekunde ngapi zilisalia?


### Response:
 Dakika 5 ni 5*60=<<5*60=300>>300 sekunde.
Sekunde 45 zimeshapita, hivyo zinabaki 300-45 = <<300-45=255>>255 sekunde.
