Coco runs a bike rental service on a resort. There are 600 bikes in Coco's fleet, out of which 50% are mountain bikes and 50% are beach bikes. Each bike is routinely taken out of service and sent to Kiko's bike-shop for maintenance and repair. On average, a mountain bike is sent to the bike-shop shop 2 times every month, and a beach bike is sent to the bike-shop 3 times every month (Assume 30 days in a month). When sent for maintenance and repair, each bike spends an average of 1.6 days in the bike-shop before it is back in service. What is the average number of Coco's vehicle out of service in Kiko's bike-shop?
