Answer:
The new ramp must be 54 inches long than the old ramp to meet the requirement of the new law
Step-by-step explanation:
Old height to length ratio is:
h : l = 2 : 15.
Height of old ramp h = 12
Length of old ramp can be find out by putting h = 12 in the above ratio
Length of old ramp = 90
Height to length ratio by current law:
h : l = 1 : 12
Height will be the same i.e. h = 12
Length of new ramp = 144
How much longer the new ramp should be to meet the new ratio law:
New length - Old length = 144 - 90 = 54 inches

Answer:
550a + 590b = 1275
Step-by-step explanation:
We use the following relation to solve this question:
In which v is the velocity, d is the distance and t is the speed.
In this question, we find the distance, so we use:
A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City.
This means that 
.
Write an equation in standard form to represent the situation if the plane travels a hours at 550 mph and b hours at 590 mph.
This means that 
.
Which equation is correctly written in standard form to represent this scenario?
1275 = 550a + 590b
550a + 590b = 1275
