Answer 1

the complete question in the attached figure

observing the graph we can say that the racing game is approximately 25% of the total
so
if 1 hour is ----------------------> 100%
  X-----------------------------25%
x=25/100------> 1/4=0.25 hours
convert to minutes
0.25*60---------> 15 minutes

the answer is 15 minutes
