A student recorded the following number of paces after walking a distance of 50 m repeatedly as 71.5, 72.0, 70.0, and 69.5. He wanted to measure the distance between two points C and D. He recorded the following number of paces from C to B or back as 465, 468, 463, and 460. What is the distance from C to D? * О 328 О 378 O 421 O 462
