What changes when a map represents more distance in each centimetre?
A prediction is a starting idea. You can revise it after exploring.
Use at least 40 characters and include an observation. Your writing is saved as evidence; it is not automatically judged for accuracy.

This is an original Bodhi learning activity. Official references establish its curriculum context, rather than endorsement of the simulation or complete syllabus coverage.

Source checked · 2026-10-21Original activities, questions, reading passages and fictional archives. A curricular connection does not make a Bodhi activity an official NCERT exercise. Broader grade adaptation awaits educator review.
Mapping under review · 2026-10-21Selected route: 5 map cm × 2 km per map cm = 10 ground km. The street route is longer than the direct segment. Doubling the km represented by each map cm doubles both ground distances.
A new route on this same map measures 7 cm. The scale is still 1 cm : 2 km. Calculate its ground distance and choose the ground unit.
The drawing is an original diagram, not a geographical survey. One grid interval is one nominal map centimetre, regardless of screen size. The 5 cm diagonal and 3 + 4 cm street route are supplied measurements; proving the diagonal is not required. Numerical scale conversion is a proportional-reasoning application; introductory Class V map work should begin with direction, symbols and comparison.
