Mark played video games for 1 hour. The circle graph shows the different types of video games he played. Based on the graph, about how many minutes did Mark play the racing game?
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
