<human>:  Samuel took 30 minutes to finish his homework while Sarah took 1.3 hours to finish it. How many minutes faster did Samuel finish his homework than Sarah?
<bot>: How many minutes did Sarah take to finish her homework? ** Since there are 60 minutes in 1 hour, then 1.3 hours is equal to 1.3 x 60 = <<1.3*60=78>>78 minutes.
How many minutes faster did Samuel finish his homework than Sarah? ** Thus, Samuel is 78 – 30 = <<78-30=48>>48 minutes faster than Sarah.
