Answer:
They will meet after 1.86 hr from the start.
Explanation:
Given that,
Distance = 250 km
The speed of A = 89 km/hr
The speed of B = 45 km/hr
The relative velocity of A w.r.to b
v_{ab}=v_{a}-v_{b}v
ab
=v
a
−v
b
v_{ab}=89-(-45)v
ab
=89−(−45)
v_{ab}= 134\ km/hrv
ab
=134 km/hr
For the time ,
Using formula of distance
The speed is equal to the distance upon time.
Now, time taken to cover a distance of 250 km with a speed of 134 km/hr is
t=\dfrac{250}{134}t=
134
250
t = 1.86\ hrt=1.86 hr
Hence, They
