To determine who drove faster without making any calculations, we can compare the distances each person drove and the time taken.
Ben drove 230 kilometers in 3 hours, while Pia drove 250 kilometers in the same amount of time (3 hours). Since both drove for the same duration, we can simply look at the distances to find out who was faster.
Pia drove a longer distance (250 kilometers) compared to Ben (230 kilometers). Therefore, since they both drove for the same amount of time, Pia must have driven faster than Ben.
