Answer: Option C
Step-by-step explanation:
Since we know the angle G, then to find the length CV we use the function of the sine.
By definition the sinx function is defined as:
Where
Opposite is the length of the side opposite the angle x.
Hypotenuse is the logitude of the side opposite the angle of 90 °
Note that in this case:
So we have to:
Now ew solve the equation for CV side:
Let x be the speed when Fritz is driving
x + 6 will be the train speed
Converting minutes to hrs
48 mins = 48/60 = 4/5 hrs
40 mins = 40/60 = 2/3 hrs
Remember formula distance = rate * time
distance driving = (4/5)x
distance train traveling = (2/3)(x+6)
The train travels the same distance as the car
4/5x = 2/3(x+6)
4/5x = 2/3x + 4
4/5x - 2/3x = 4
basic elementary school math
2/15x = 4
2x = 40
x = 30 miles/hrs is the speed he driving.
distance train traveling = 2/3(30 + 6) = 24 miles
check with the distance he driving
4/5(30) = 24 miles
