Answer:
Maria made 248 cookies, Denise made 62 cookies, Joseph made 372 cookies.
Step-by-step explanation:
Number of cookies made by Maria is m,
made by Denise is d,
made by Joseph is j
We can write the following equations from the word:
m = 4d
j = 6d
m + d + j = 682
We can substitute both 1st and 2nd equation in 3rd and solve for d:
m + d + j = 682
4d + d + 6d = 682
11d = 682
d = 62
Thus,
m = 4(62) = 248
and
j = 6(62) = 372
Maria made 248 cookies, Denise made 62 cookies, Joseph made 372 cookies.

Answer:
Toshi must begin his walk at 11:00 AM in order that he can return by 8:00 PM.
Step-by-step explanation:
Since the Gotemba walking trail up Mount Fuji is about 9km long, and walkers need to return from the 18km walk by 8pm, if Toshi estimates that he can walk up the mountain at 1.5km / h on average, and down at twice that speed , these speeds taking into account meal breaks and rest times, to determine what is the latest time he can begin his walk so that he can return by 8pm the following calculation must be performed:
Climb: 1.5 km / h
Descent: 2 x 1.5 km / h = 3 km / h
Climb: 9 km / 1.5 km / h = 6 hours
Descent: 9km / 3 km / h = 3 hours
Total: 9 hours
8 PM = 20:00
20:00 - 09:00 = 11:00
Thus, Toshi must begin his walk at 11:00 AM in order that he can return by 8:00 PM.
