hmm, I see, she left at 8am, and forgot her lunch anyhow so how long do you think Will would have traveled in distance when he catches up with her? would you say by that time they'd have traveled the same distance?
10 minutes = 10/60 = 1/6 hours let t = time elapsed (in hours) from when Grace leaves home If Grace walks at 5 km/hr, then she will walk a total of 5t kilometers when she walks for t hours. Will starts ten minutes or 1/6 hour later, so he will bike for t - 1/6 hours. This means he travels 15(t -1/6) km
say, you leave home at 8am, and then your brother catches up with you by the time your brother, also from home, catches up with you, you have already walked 2 miles how long has he walked too?
if you had walked 2 miles, and your brother walked 3 miles so he really passed you by, by 1 mile if you had walked 2 miles, and your brother walked 1 mile so he's still 1 mile behind you if you had walked 2 miles, and your brother walked 1 1/2 miles he hasn't gotten to you, he's still behind
however if you walked 2 miles, and he walked 2 miles, both from home has he caught up with you? or pass you by or still behind you?
you aren't making sense.. can u just tell me what goes in the chart then tell me the equation??
well, that's the idea behind it
can u tell me itd be helping me
anyhow, jim_thompson5910 already typed it in
grace walks 5t km will bikes 5(t-1/6) km the two will meet when the two distances are the same, so you need to solve 5t = 5(t-1/6)
will bikes 15(t-1/6), so the equation should be 5t = 15(t - 1/6)
how do u solve with the 1/6??
5t = 15(t - 1/6) 5t = 15t - 15(1/6) ... distribute 5t = 15t - 15/6 ... multiply 5t = 15t - 5/2 ... reduce I'll let you finish up
subtract 5t next?
???? is that right
T=-1/2 answer so -1/2 hours
5t - 15t = ???
i didn't put that anywhere
what is 5t - 15t
simplify 5t - 15t for me
so we now have -10t = -5/2 t = ??
it's positive though
t = 1/4
so it takes 1/4 of an hour or 15 minutes for Will to catch up to Grace
how long would that be??
oh ok 15 or 1/4 of an hour. THANKS SO MUCH im posting another question sticka round
3.) a jet took one hour longer flying to Lincoln from Adams at 800 km/h than to return at 1200 km/h find the distance from Lincoln to Adams????
