Answer:
210 seconds.
Step-by-step explanation:
Given,
The time taken by jasmine's dessert = [tex]3\frac{1}{2}[/tex] minutes,
We know that,
1 minute = 60 seconds,
Hence, the time taken by jasmine's dessert
[tex]= 60\times 3\frac{1}{2}[/tex]
[tex]=60\times \frac{7}{2}[/tex]
[tex]=\frac{420}{2}[/tex]
[tex]=210\text{ seconds}[/tex]
