It demonstrates how to adjust after rounding by taking away or compensating for the extra minutes introduced during the approximation. The key includes an example (e.g., 6:25 + 1 hour and 55 minutes) and then supplies final elapsed-time answers for problems 1 through 20. Answers cover a mix of hour-minute additions, subtraction of rounding adjustments, and resulting times.",{"@graph":14,"@context":72},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/exam/","Exam",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/determining-time-using-rounding-answer-key-483051/483051/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/determining-time-using-rounding-answer-key-483051/483051.png","ImageObject",300,407,{"name":42,"@type":43},"Indoniesian Boy","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-09-30",true,{"@type":52,"interactionType":53,"userInteractionCount":33},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"How does the worksheet determine time using rounding?","Question",{"text":62,"@type":63},"It rounds minutes to the next hour first to make the addition easier, then adjusts by accounting for the extra minutes created by the rounding.","Answer",{"name":65,"@type":60,"acceptedAnswer":66},"What is the purpose of subtracting minutes after rounding?",{"text":67,"@type":63},"After rounding up to the next hour, the method subtracts the difference (for example, 5 minutes) so the final result matches the true elapsed time.",{"name":69,"@type":60,"acceptedAnswer":70},"Does the answer key provide results for all problems?",{"text":71,"@type":63},"Yes.
