He was 1 minute 28 seconds faster.

Step-by-step explanation:

Hi, to answer this question we simply have to subtract Frankie's time yesterday (29 minutes 49 seconds) to his normal time (31 minutes 17 seconds)  

Mathematically speaking:  

31m 17s - 29m 49s =

(31m-29 m) (17s-49s)=

2m -32s=

1m 60s -32s=

1m 28s

He was 1 minute 28 seconds faster.
