If one is at a speed of 35 mph and the other 60, sum the speeds to work with just one number:
35 + 60 = 95mph
The formula for time is:
Time = Distance / Speed
Time = 855 / 95
Time = 9h (D.)
Hope it helped,
Happy homework/ study/ exam!
Answer:
Market price $400
Cost price $300
Step-by-step explanation:
MP: market price
CP: cost price
1. (MP x 0.9) - CP = 60
CP = 0.9MP - 60
2. MP - CP = 100
CP = MP - 100
0.9MP - 60 = MP - 100
MP - 0.9MP = 100 - 60
0.1MP = 40
MP = 400
Cost price = MP - 100 = 400 - 100 = 300

Answer:
are zeroes of given quadratic equation.
Step-by-step explanation:
We have been a quadratic equation:
We need to find the zeroes of quadratic equation
We have a formula to find zeroes of a quadratic equation:
General form of quadratic equation is 
On comparing general equation with b given equation we get
a=2,b=-10,c=-3
On substituting the values in formula we get
Now substituting D in 
we get
Therefore,
Interest I = PRT /100
P = $ 1000
R = 5.5% per annum
T = 18 months = 18 /12 = 1.5 years.
I = 1000 * 5.5 * 1.5 /100
I = $ 82.5
Amount = P + I = 1000 + 82.5 = 1082.5.
Hence the it would have grown to $1082.5
