Michael wants to dig a hole 400 feet less deep than twice the depth of the hole that his father dug. The father dug a hole at a rate of 4 feet per hour. If the father took 400 hours to dig his hole, how many hours will it take for Michael to dig a hole that is 400 feet less than twice as deep as his father's hole working at the same rate?
Майкл мехоҳад, ки як чуқурии 400 фут камтар аз ду баробари чуқурии чуқурие, ки падари ӯ канд, канд. Падар чуқуриро бо суръати 4 фут дар соат канд. Агар падар 400 соат барои кандани чуқурии худ сарф кунад, Майкл барои кандани чуқурие, ки 400 фут камтар аз ду баробари чуқурии чуқурии падари ӯ бошад, бо ҳамон суръат чанд соат сарф мекунад?
How deep was the father's hole? ** Since the father dug a hole with a rate of 4 feet per hour, if the father took 400 hours digging the hole, he dug a hole 4*400 = <<4*400=1600>>1600 feet deep.
How deep is the hole that Michael's father dug? ** Twice the depth of the hole that Michael's father dug is 2*1600 = <<2*1600=3200>>3200 feet
How deep does Michael want to dig? ** Michael wants to dig a hole 400 feet less than twice the depth of the hole that his father dug, meaning he wants to dig a hole 3200-400 = 2800 feet deep.
How many hours will it take Michael to dig a hole that is 400 feet less than twice as deep as his father's hole working at the same rate? ** To dig a hole that is 400 feet less than twice as deep as his father's hole working at a rate of 4 feet per hour, Michael will have to work for 2800/4 = 700 hours.

How deep was the father's hole? ** Азбаски падар як чуқурии 4 фут дар соат канд, агар падар 400 соат барои кандани чуқурӣ сарф кунад, ӯ як чуқурии 4*400 = <<4*400=1600>>1600 фут канд.  
How deep is the hole that Michael's father dug? ** Дучандии чуқурии чуқурие, ки падари Майкл кандааст, 2*1600 = <<2*1600=3200>>3200 фут аст.  
How deep does Michael want to dig? ** Майкл мехоҳад, ки як чуқурии 400 фут камтар аз дучандии чуқурии чуқурие, ки падари ӯ кандааст, канда, яъне ӯ мехоҳад, ки як чуқурии 3200-400 = 2800 фут канда.  
How many hours will it take Michael to dig a hole that is 400 feet less than twice as deep as his father's hole working at the same rate? ** Барои кандани чуқурие, ки 400 фут камтар аз дучандии дучандии чуқурии падари ӯ аст, бо суръати 4 фут дар соат, Майкл бояд 2800/4 = 700 соат кор кунад.
