Maths Fun with Caspar Lee

If Caspar can fill a car with Maltesers in 3 hours and Conor can fill it in 5 hours, can you find out how long it takes them to fill it together? (Not 4 hours!)

Hope you like the challenging problem I did with Caspar on rates & ratios! Please feel free to comment below if you have any suggestions for more fun questions :)
