The distance between two cities is 100 mi. Is the number of kilometers between the two cities larger, smaller, or equal to 100?
a) equal to 100
b) smaller than 100
c) larger than 100
♦ Relevant knowledgeIt is common to use proportions between distances by using scales that are represented on maps. It is common to come across situations where the two numbers are actually multiples of one other. If we are comparing two proportional values with the quotient, we obtain an equal value. An illustration of proportional values can be observed in the scale of maps.
1 mile = 1.609km
100 miles = 100*1.609km
= 160.9 km
Number of kilometers greater than 100
