Could anyone tell me how the first question works because I was confused on it I thought the 900kg car with 20km was correct because it weighs less so is the 1,200 kg that goes 20km more efficient because it weighs a lot and travels more? If that makes sense

1.a 1,200 kg car that travels 20 km per liter of fuel

where is the first star located in"Hands-on hall" In super mario 3d world?

Answer 64

In Super Mario 3D World, the first star location in Hands-On Hall can be found by heading to the first moving platform section. Along the way, jump onto the first platform and look to your right to see a breakable wall. Break it using an attack or by ground-pounding and head inside to find the first star.
