Whose car goes the furthest?

The twins, Mike and Mary, have each received a toy car for their birthday. They have been pushing them along the floor and letting them go. Both cars went quite a long way.

Then Mike started boasting. “My car will go much further than yours,” he said. “No, it won’t” said Mary, “mine will go much further than yours.” “No, it won’t,” Mike repeated, until eventually they started arguing and shouting at each other.

They started to push the cars faster and harder but couldn’t agree which of their cars would go the furthest. Can you help them stop arguing with each other?
