OK.......
So,
ON MONDAY:
Time spent on patrol = 4.5 hrs
Time spent on surveillance = 2 hrs
ON TUESDAY:
Time spent on patrol = 3 hrs
Time spent on surveillance = 1 hr 40 min
Now,
The question is asking us the ratio of
<u>surveillance to patrol</u><u /> so, the value of surveillance needs to be on the top.
So,
Let's first change all the units to common units.....i.e. either hrs. to minutes or minutes to hrs.
In this case .....i think it will be easier to convert minutes to hrs.. because if we do that ...we only have to do one conversion.
So,
1 hr. 40 minuter = 1hr + (40 /60) hrs
= 1 + 0.67
= 1.67 hrs
So,
ON TUESDAY:Time spent on surveillance = 1.67 hrs
Now,
Let us find the ratio of surveillance to patrol on both days:
ON MONDAY:
Ratio of surveillance to patrol =
ON TUESDAY:Ratio of surveillance to patrol =
Now,
If we look at the ratio, the ratio of
TUESDAY sure is greater than ratio on
MONDAY<u>
</u><u>
So, Tuesday has a greater ratio of time on surveillance to time on patrol</u>
