7,452 seconds
                               

Answer 2

Answer:  The race lasted for 7452 seconds.

Step-by-step explanation:  Given that a car race lasted 2.07 hours.

We are to find the number of seconds for which the race lasts.

We know that

1 hour = 60 minutes = 60 × 60 seconds = 3600 seconds.

So,

$2.07~\textup{hours}=2.07\times 3600~\textup{seconds}\\\\\Rightarrow 2.07~\textup{hours}=7452~\textup{seconds}.$

Thus, the race lasted for 7452 seconds.
