Answer 1

if an hour is equal to 1, then we know that the answer is more than 3. 12 minutes is equal to 1/5 of an hour, and if we add 3 and 1/5, we get the answer.

3 1/5

Answer 2

Jake's running time as a decimal is:

3.2 hours

Explanation:

We are given that:

Jake completed a marathon race 3 hours and 12 minutes.

We know that:

1 hour= 60 minutes

1 minute= 1/60 hour

12 minutes = 12/60 minutes

= 0.2 hour

3 hours and 12 minutes= (3+0.2) hours

= 3.2 hours

Hence, Jake's running time as a decimal is:

3.2 hours
