Problema Solution
craig drives 20 km/hr faster than marilyn. in the same time that marilyn drives 225 km, craig drives 325 km. find the speed of each car.
Answer provided by our tutors
Let v is velocity of Marilyn, and hence v + 20 is velocity of Craig.
We have:
225/v = 325/(v+20)
100v = 4500
v = 45
Therefore:
- Marilyn: 45km/hr
Craig: 65km/hr
