4 x 25 = 100 metres = 0.1 km
40 x 25 = 1,000 metres = 1 km
80 x 25 = 2,000 metres = 2 km
1 km = 1000 m. 2.5 kms = 2500 m. 2500 m divide by 50 m (length of pool) = 50 laps

100cm in a metre 1000m in a km 2km = 2000m In cm's, this is equivalent to ( 2000 x 100) or 200,000 cm
olympic pool length is 50 meters. thus, 15 lengths would be 750 meters. finally, if you consider a lap a roundtrip, 7 1/2 laps would be .75 km.
