Answer:
The distance of Stephan's root is 3.125 km
Step-by-step explanation:
To solve the question we follow each of the statements individually one after the other calculating the values as we proceed.
Anya's route is 21/4 kilometers
Jose's is 11/2 fewer kilometers than Anya's routem= 21/4 -11/2 = 3/4 kilometers
Cali's route is 11/2 times as long as Jose's route which is equal to 3/4×11/2 =9/8 km or 1.125 Km
Cali's route is 2 km fewer than Stephan's route
Therefore Stephan's route is equal to 2 km + Cali's route or = 2 + 1.125 = 3.125 km
