Answer:
Total distance covered: 60x8 = 480
Speed needed to cover distance of 480 km in 6 hrs = 480/6 = 80 km/hr.
initial velocity : 60 km/hr.
Train needs to run faster with speed of 20km per hour to achieve same distance in 6 hrs.
Step-by-step explanation:
Answer:
-1, -2, -3 Are all consecutive
Step-by-step explanation:
-1 + -2 + -3 = -6
30n^2(that arrow then 2 means squared)+321n+210
STEP BY STEP:
13x - 8 + 7x – 2 = 11+ 6x -- 14x – 5
Combine like terms
20x-8-2 = 20x+11-5
20x-10 = 20x+6
Subtract with -20x on both sides and the result is:
![-10\neq 6](https://tex.z-dn.net/?f=-10%5Cneq%206)
The answer is NO SOLUTION
