Answer:
Truck D.
Step-by-step explanation:
Below are the rates of travel of 4 shipping trucks.
Truck A: 300 miles in 4 hours Truck B: 240 miles in 3 hours Truck C: 325 miles in 5 hours Truck D: 170 miles in 2 hours.
Speed = distance/time
Speed of Truck A,
![v_A=\dfrac{300}{4}\\\\v_A=75\ mph](https://tex.z-dn.net/?f=v_A%3D%5Cdfrac%7B300%7D%7B4%7D%5C%5C%5C%5Cv_A%3D75%5C%20mph)
Speed of Truck B,
![v_B=\dfrac{240}{3}\\\\v_B=80\ mph](https://tex.z-dn.net/?f=v_B%3D%5Cdfrac%7B240%7D%7B3%7D%5C%5C%5C%5Cv_B%3D80%5C%20mph)
Speed of Truck C,
![v_C=\dfrac{325}{5}\\\\v_C=65\ mph](https://tex.z-dn.net/?f=v_C%3D%5Cdfrac%7B325%7D%7B5%7D%5C%5C%5C%5Cv_C%3D65%5C%20mph)
Speed of Truck D,
![v_D=\dfrac{170}{2}\\\\v_D=85\ mph](https://tex.z-dn.net/?f=v_D%3D%5Cdfrac%7B170%7D%7B2%7D%5C%5C%5C%5Cv_D%3D85%5C%20mph)
It can be seen that the speed of Truck D is more out of Trucks A,B and C. Hence, Truck D is moving at a faster rate.
Answer:
6x-7y=17-----y=6/7x-17/7
6x-11y=-13----y=6/11x-13/11
6x-11y=13----y=6/11x+13/11
11x-6y=13-----y=11/6x-13/6
