Distance equals rate times time. For each of your given rates and times, calculate the distance represented. The total distance is the sum of all your calculated distances. The 14.9 minutes getting gas and eating is a red herring; it has nothing to do with your final answer since the distance traveled at 0 kilometers per hour for any amount of time is still 0 kilometers.
