1.65 minutes
Step-by-step explanation:
10 9/10 + 5 3/5 = 16 1/2
16 1/2 divided by 20 = 1.65 or 33/20
We have to express the ratio 1 : 3.5 in the form p:q where p and q are whole numbers.
Consider the ratio of 1 and 3.5,
1 : 3.5 = 
= 
Reducing the above fraction to its lowest form.
So, we get 
Therefore, the ratio 1 : 3.5 is expressed as 
where 2 and 7 are the whole numbers.
