By definition we have the following equation:
t = d / v
Where,
t: time
d: distance
v: speed
For this case we have:
d / 30 + d / 4 = 17
Rewriting we have:
2d + 15d = 17 (60)
17d = 17 (60)
d = 60 mi
Then, the walking time is
t = d / v
t = 60/4
t = 15 hours
Answer:
She walked
t = 15 hours
Answer:
7.51
Step-by-step explanation:
the hundredth place is the place 2 after the decimal. if the number after that is 5 or more, you round the number up, and if it is four or less you round the number down. so, it would be 7.51
Answer:
y=-1/4x-5 1/2.
Step-by-step explanation:
Using the formula y-y1=m(x-x1), plug in the slope and the numbers and you'll get y=-1/4x-5 1/2.
Out of what? Nothing is shown. :(
I think the answer is A. Cause your supposed to subtract so 7n-4n=3n, and 3-2=1 :) I hope this helps
