In a mechanical system involving interconnected wheels, the direction and speed of rotation often depend on their arrangement and how they are connected. If wheel 1 is rotating in one direction, wheel 4, depending on the gearing or connection type, could rotate in the opposite direction.

When considering wheel 4 in relation to wheel 1, if it's determined that wheel 4 rotates anticlockwise, this indicates a typical mechanism where wheels are designed to rotate in opposite directions due to their engagement.

The phrase "and slower than wheel 1" suggests that the gearing ratio between the two wheels is such that wheel 4, despite rotating in the opposite direction, is less efficient in its speed due to the torque being exerted differently or because of a larger diameter relative to wheel 1. This could mean that wheel 4 provides more force but at a lower speed—an important principle in mechanical systems known as the trade-off between speed and torque.

Thus, the understanding of mechanical properties, including gear ratios, rotational direction, and the relationship between speed and torque, leads to the conclusion that wheel 4 indeed rotates anticlockwise and at a slower pace compared to wheel 1.
