Answer:
Rate of slower bus; 90 km/h
Rate of faster bus; 102 km/b
Step-by-step explanation:
We know that formula do distance is;
Distance = speed/time
We are told that One bus travels 12h slower than the other.
Let speed of slower bus be x.
Thus;
Speed of faster bus = x + 12
Speed of slower bus = x
After 3 hours, distance by faster bus = 3(x + 12)
Speed of slower bus = 3x
Since the towns are 576 km apart, then;
3(x + 12) + 3x = 576
Divide through by 3 to get;
x + 12 + x = 192
2x + 12 = 192
2x = 192 - 12
2x = 180
x = 180/2
x = 90 km/h
Faster bus speed = 90 + 12 = 102 km/h
2.0076* 10^4
move the decimal 4 places to the right
20076.
20076 < 26970
X= 38.12325882663022
First take SOHCAHTOA
We’ll use SOH.
SOH means sine(angle)=opposite/hypotenuse.
So sine(43 degrees)=26/X
Which means 26/(sine(43 degrees))=X
Which means 26/0.681998360062499=X
