When you factor the equation...
r^2-4r-77
r^2+7r-11r-77
r(r+7)-11(r+7)
(r-11)(r+7) so each parenthetical term is a dimension.
Note that r>11 though for any possible real solution.

The time taken to reach train from Zurich to Paris is 8 hours 52 minutes.
Step-by-step explanation:
The given is,
Train leaves Zurich at 22:40
Train arrives Paris at 07:32
Step:1
Time taken to reach from zurich to paris,
= Train leaves at Zurich - Train arrives at Paris
= 22:40 - 07:32
= 8.52 hours
Step:2
Time taken by train to reach from zurich to paris in minutes,
= 8.52 hours
= 4831 minutes 12 secs
Result:
The time taken to reach train from Zurich to Paris is 8 hours 52 minutes, if a train leaves Zurich at 2240 and arrives in Paris at 0732.
is the formula you need do you divide 47.1 by 2 and
so its aproximatly 7.5 or 7.496
There you go. cube root of smth is just the value to the power of one third.
