Is this a trick question? the answer is 7.5 hours, because there are 60 minutes in a hour so you divide 450 by 60 and you get 7.5
None, but there are 450 minutes in 71/2 hoursTo find this:Divide 450 by 60 (450 / 60)That equals 7.5.But how do we calculate this as precise hours and minutes?Take 7.5; this is 7.5 hours. The .5 is a half; so what's half of an hour? 30 minutes?So this becomes 7 hours and 30 minutes.Short method:450 / 60 = 7.5 = (.5 means half so 30 mins) = 7 hours and thirty minutes.
Dividing distance travelled by speed gives 450/65 = 6.923076 recurring (that is, 6.923076923076...) hours or 415 minutes, rounded to the nearest minute.
