Given:
The two cars met at t= 5 hours
Car A leaves at t=0
Car B leaves at t = 4.5 hours, so only traveled for only 0.5 hours.
Car B travels 150 kilometers
so d = distance from A to B
As a result, Car A travels d - 150 km
150 = (Vb) * (0.5) ---> time of travel which is 0.5 hours
divide both sides by 0.5, you'll get Vb = 300 km/h this is the speed of Car B
Va = Vb - 10km/hr
Va = 300 - 10km/hr
Va = 290 km/hr is the speed of Car A
so:
d - 150 = (Va) * t
d - 150 = 290 * 5
d - 150 = 1450
d = 1450 + 150
d = 1600 km
The distance between Car A and Car B is 1600 kilometers.
