Karen is planning to drive 2421 miles on a road trip. if she drives 269 miles a day, how many days will it take to complete the trip?

It would take Karen 9 days to complete the trip.

Divide the total of 2421 miles by the 269 miles a day, which gives you 9. Therefore, it would take her 9 days to finish the trip.

2421÷269=9

answer: a clock

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
