Problema Solution
Jose ran twice as many kilometers as Karen. Adding 8 to the number of kilometers Jose ran and dividing by 4 gives the number of kilometers Maria ran. Maria ran 3 kilometers. How many kilometers did Karen run?
Answer provided by our tutors
Let Karan runs x km.
then jose runs 2x km.
so, maria runs (2x+8)/4 km.
but in question it is given that maria runs 3 km
=> (2x+8)/4 =3
=> 2x+8=12
=> 2x=12-8 =4
=> x=2
so, karen runs 2 km.
