Problema Solution
Elena bicycles 4km/h faster than Praedup. In the same time it takes Praedup to bicycle 42 km, Elema can bicycle 54 km. How fast does each bicyclist travel
Answer provided by our tutors
Let Pradeeps' speed be x km/hr
Let Elema's speed be=x+4 km/hr
Time taken by Pradeep to travel 42 km=42/x hrs
Time taken by Elema to travel 54 km=54/(x+4) hrs
42/x=54/(x+4)
42(x+4)=54x
168=12x
x=14 km/hr
Pradeep's speed=14 kmph
Elema's speed=18 kmph
