Question

My house is 20 miles from yours, but on the map it is only 4 mm away. What is the scale of the map? O A Imm = 5 mi B. I mm = 20 mi Oci mi = 20 mm OD 20 mm = 4 m E Smi= 4 mm​

Answer 1

$\huge \bf༆ Answer ༄$

Let's use Unitary method to solve the question ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:4 \: mm \rightarrow20 \: miles$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:1 \: mm \rightarrow(20 \div 4) \: miles$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:1 \: mm \rightarrow5 \: miles$

Therefore, 1 mm corresponds to 5 mile according to the map.

so, correct choice is ~

$\overbrace{ \underbrace{\underline{ \boxed{ \sf A }}}}$
