[ [motion problems ]

Two people set off from A to B at the same time. The first one rode a bicycle, while the second one drove a car at a speed five times greater than the first one's. Halfway through, the car had an accident, and the driver walked the remaining distance on foot at a speed half that of the cyclist. Who arrived in $B$ first?
A cyclist moves twice as fast as a pedestrian, so he can cover the entire distance in the time it takes the pedestrian to cover half the distance. But at the moment the pedestrian started, the cyclist had already covered some distance. Therefore, the cyclist arrived earlier.

## Answer

The cyclist.
