Question

Town A and B are 390 km apart. A car travels from town A at 70 km/h. At the same time
a Van starts to travel at 60km/hr from Town B. When and where do the car and the van
meet each other?

Answer 1

$Speed =\frac{Distance}{Time}$

$Time=\frac{Distance}{Time}$

Distance=390Km

Speed of car=70km/h

Speed of van =60km/h

Since the two vehicles are travelling at different directions;

The total speed = 70+60=130km/h

$Time=\frac{390km}{130km/h}=3hrs$

The and the van will meet after 3hrs

The two vehicles will met at

$Distance=speed×time$

Meeting point =70km/h×3h=210km

The meeting point will be 210km from town A
