Answer:
32km/hr
Explanation:
The question asks to calculate the average speed for a boat.
Mathematically, the average speed is the total distance divided by the total time
Let’s get the total distance traveled:
That would be 70km + 26km = 96km
Now the total time taken would be 3 as the boat did not move at all for an hour.
The average speed is thus 96/3 = 32km/hr

The primary distinction between the digestive systems of cows and humans is that the former uses a foregut fermenter while the latter uses a straightforward monogastric digestion. The types of teeth, mouths, stomachs, guts, and digestive enzymes released by the gut also vary between the two digestive systems. Cows and humans have different digestive systems because they have evolved two different sorts of dietary patterns based on their capacities. The primary distinctions between the digestive systems of cows and humans are in the types of teeth, mouths, stomachs, and intestines, as well as the enzymes released.
Explanation:
It is known that molarity is the number of moles present in a liter of solution.
Molarity = 
Also, number of moles equal mass divided by molar mass. And, molar mass of calcium is 40.07 g/mol.
No. of moles = 
= 
= 0.025 mol
Therefore, calculate the molarity as follows.
Molarity =
= 
= 0.025 M
Thus, we can conclude that molarity of 
in milk is 0.025 M.
