Answer:
y = 6
Step-by-step explanation:
If x = 1, then: 3 x 1 + y = 9 (first equation)
3 x 1 + y = 9
3 + y = 9
y = 9 - 3
y = 6
It's known that Speed = Distance/Time. The truck can cover the distance of 145 miles in 2.5 hours. So its speed is 145/2.5 = 58 mi/hr. The speed of the car is 1.5 faster than the speed of the track. So the speed of the car is 58*1.5 = 87 mi/hr.
Let t = amount of time, in hours, it takes them to meet.
The distance that the truck travels in t hours would be 58t miles.
The distance that the car travels in t hours would be 87t miles.
In total they cover the whole distance when they meet. So we get
58t + 87t = 145
145t = 145
Divide both sides by 145:
t = 1
Thus it takes them 1 hour to meet.
