Be aware that "book" airspeeds don't often happen in the real world, and
there are big differences in economical cruise speed between apparently
similar aircraft. In an old rental 172 160 without wheel pants, count on
100 knots TAS (115mph), less in a 152, not much more in a 172 180. Older
Cherokees have comparable airspeed to Cessnas with the same engines.
