plz telll me ....​

Answer 1

Step-by-step explanation:

In the past,

Time taken by Pintu to finish race = 29.8 seconds

Time taken by Amu to finish race = 28 seconds

Present Timings,

Time taken by Pintu = 25 seconds

Time taken by Amu = 31.5 seconds

Comparing the timing,

Pintu = 29.8 - 25 = 4.8 seconds

Pintu now improved by 4.8 seconds.

Amu =31.5 - 28 = 3.5

Amu now exceeds by 3.5 seconds.

Therefore, Pintu improved by her timing by 4.8 seconds.

Thank you!
