The packaging lists a model airplane’s length as 15 in. It also gives the scale as 1:78. What is the length of the actual airplane to the nearest foot?
we know that [scale]=measure model airplane/measure actual airplane scale=1/78 measure actual airplane=measure model airplane/scale measure actual airplane=15/(1/78)----> 15*78-----> 1170 in
1 ft------------> 12 in X---------> 1170 in x=1170/12-----> 97.5 ft-------> 98 ft
