I was watching the street, there were mopeds(2 wheels) bikes(2 wheels), tricycles(3 wheels), taxis(4 wheels) and big trucks(6 wheels). I counted as they went past a total of 60 in 5 minutes. I notice the following about the vehicle. Every second was a taxi. Every odd prime numbered vehicle was human powered.so the 3rd, 5th, and 7th,11th, 13th and so on, three out of every four human powered vehicles were a bicycle. The odd multiples of 3(not included 3) were mopeds.and the remaining was big trucks. How many wheels went by on these 60 vehicles?
