When the two vehicles catch up, the distance traveled by them will be equal. We also know that: distance = velocity * time
Let us say that the car has traveled for time t hours. Thus, the bus will have traveled for t + 1.5 hours: For the car: s = 60t For the bus: s = 40(t + 1.5)
Equating: 60t = 40(t + 1.5) 20t = 60 t = 3 hours
The distance traveled in this time will be: s = 60 * 3 = 180 miles
3. Using antibiotics the wrong way is making them not work as well.
