Question

find the ratio of 30 minutes to 1.5 hours

Answer 1

We know that 1 hour = 60 minutes

                Then 1.5 hour = 1.5 * 60

                                       = 90.


The ratio of 30 minutes to 1.5 hours = 30/90

                                                             = 1:3.


Hope this helps!

Answer 2

Hey.

We have to find the ratio of 30 mins to 1.5 hrs.

We should remember that while comparing two quantities, we must see that whether they are in same unit or not.
e.g. km and m are different units of distance.
hr and min are difference units of time.
Joule and Kilojoule are different units of energy.
So we should convert them in one unit.

So. let us move to the question.....

30 minutes and 1.5 hrs.

Let us convert them in minute.

30 mins
1.5 hrs = 1.5 × 60 = 90 mins
( As 1hr = 60 minutes)
So.

$\frac{30}{90} \\ = \frac{1}{3}$
= 1:3

Hence, the ratio of 30 minutes to 1.5 hrs is 1:3.
