The pole vaulter cleared the bar at 490 cm. Convert 490 cm to meters using a unit multiplier.

245 cm

250

490cm * 1m/100cm = 4.9m

To convert centimeters to meters, we need to remember that there are 100 centimeters in 1 meter. To convert 490 centimeters to meters, we can use the following unit multiplier:

490 cm * (1 m / 100 cm)

Here, we multiply 490 cm by the fraction (1 m / 100 cm). By doing this, the centimeter units cancel out, leaving us with the desired meter unit.

The calculation would be:

490 cm * (1 m / 100 cm) = 4.9 m

Therefore, the pole vaulter cleared the bar at a height of 4.9 meters.
