THE DISTANCE BETWEEN TWO PLACES X AND Y ON MAP IS 6 INCH AND R.F IS 1: 31680 FIND OUT THE AVCTUAL DISTANCE BETWEEN THESE TWO PLACES
Answers
Answer:
So for a distance of 3 cm the distance on the ground between the cities will be 600,000 cm which is 6000 meters or or 6 km. In normal circumstances the distance will be quoted in the largest units so this distance will be called 6 km rather than 6000 meters.
Given :- The distance between two places X and Y on map is 6 inch and RF is 1 : 31680 . find out the actual distance between these two places .
Answer :-
we have given that,
→ Representative fraction (RF) = 1 : 31680 .
which means that, for every 1 unit(given in inch) distance, it will be 31680 units in actual distance .
so,
→ 1 inch = 31680 inch
→ 6 inch(given) = 31680 * 6 = 190080 inch .
now, we know that,
→ 1 inch = 2.54 cm
→ 190080 inch = 479001.6 cm
now,
→ 1000*100 cm = 1 km
→ 479001.6 cm = (479001.6/1000*100) = 4.790016 ≈ 4.8 km (Ans.)
