<span>speed = distance/time
total time is 8 hours
outgoing speed is 160 km per hour,
so time = d/160
</span><span>returning speed is 240 km per hour,
so time = d/240
d/160 + d/240 = 8
3d/480 + 2d/480 = 8
5d/480 = 8
5d =480 (8)
5d = 3840
d=3840/5
d=768
answer: so the distance is 768 km</span>
Answer:
5 1/4 cups
Step-by-step explanation:
7x3/4= 5 1/4
100/298 = .3355704698 but the answer in a fraction in simplest form is 50/149
Differentiate the given solution:

Now, given that <em>x</em> (<em>π</em>/4) = √2/2 … (I'm assuming there are symbols missing somewhere) … you have



Similarly, given that <em>x'</em> (<em>p</em>/4) = 0, you have



From this result, it follows that

So the particular solution to the DE that satisfies the given conditions is
