Read before answering

An ideal 42 km journey has constant positive speed v km/h and time t=42/v hours. Use a SEPARATE sheet of squared paper: horizontal v from 0 to 12, vertical t from 0 to 42, with labelled units and a regular scale. Calculate points at v=1,2,3,4,6,12; draw a smooth curve through them, not straight segments. The origin is not a point on this curve. Do not join to v=0.
