70 = 29 + x
x = 41 ft
Answer:
v = 72 km/h
Step-by-step explanation:
Given that,
The distance covered by the Patrick, d = 288 km
Time taken, t = 4 hours
We need to find the average speed of Patrick. We know that the average speed of an object is equal to the total distance covered divided by total time taken. Let it is v. So,

So, his average speed is equal to 72 km/h.
Answer:
140 ounces of water and 105 ounces of 35% salt solution.
Explanation:
Let
be the ounces of water that need to be added and
be the ounces of 35% solution that need to to be added.
We know that the total of ounces of water and of 35% solution must be 245 ounces:

35% of
is the salt, and since no salt is added with addition of
liters of water, this must be equal to the amount of salt in the final 15% solution:

we solve for
and get:

We put this value into
and solve for
to get:

Thus we have 140 ounces of water and 105 ounces of 35% solution.
