Step-by-step explanation:
Answer:
20 mph
Step-by-step explanation:
Let speed of Train a = Va mph
Let speed of Train b = Vb mph
Va = Vb + 30
Let time taken for Train a = Ta
Let time taken for Train b = Tb
time taken = distance travelled/speed
Ta = 350/Va = 350/(Vb+30)
Tb = 140/Vb
But they both travel in the same amount of time.
So, Ta = Tb
Cross multiply
Divide both sides by 210

For this we would first simplify using order of operations.
6(-3-x) - 2x = 14 ------> Distribute
-18 -6x - 2x = 14 ------> Combine Like Terms
-8x - 18 = 14 Now we want to isolate x!
-8x - 18 = 14 ------> Add 18 to both sides.
-8x = 32 ------> Divide both sides by -8.
x = -4
Hope this helps!
