Two locomotives approach each other on parallel tracks. Each has a speed of 95 km per h with respect to the ground. If they are initially 8.5 km apart, how long will it be before they reach each other?

Respuesta :

Answer:

t = 0.045 hr

Explanation:

given,

speed of the car A = 95 Km/h

speed of car B = 95 Km/h

initial distance = 8.5 Km

time = ?

now,

the relative speed between the two vehicle

= 95 - (-95) = 190 Km/h

we have use negative speed because one car is moving opposite to other.

we know,

distance = speed x time

[tex]t = \dfrac{distance}{speed}[/tex]

[tex]t = \dfrac{8.5}{190}[/tex]

t = 0.045 hr

time taken the car to reach each other is equal to 0.045 hours.
