1749 should be rounded to 1700 because 1749 is closer to 1700 than to 1800
1750 should be rounded to 1800 because it is equally close to 1700 and 1800, and so you apply the rule than when the number to round finish in 5 you round to the next upper number.
Now, if you apply the same 1849 should be tha greater number that when rounded to hundreds becomes 1800.
So, the smalles and largest numbers of pupils there could be in the school are 1849 and 1750, respectively.
We need to solve the speed formula for d. To do so, let's start by moving the number of the left hand side:

Square both sides to get rid of the square root:

Now plug the known value of the speed to find the distance:

So the closest answer is the last one: d=0.155km
3√10 + 7√15 - 6√10 - 4√15
3√10 - 6√10 + 7√15 - 4√15
-3√10 + 3√15
The answer is B.
