Answer:
C
Step-by-step explanation:
Complementary angles add up to 90°, so you can use the equation, 90°= 67°+X°. To solve this, you need to subtract 67° from both sides to get 23°=X°
The rate(speed) is 1 3/5
We can use the distance formula to solve:
d= rt
D= 4/5
T=1/2 hr
Substitute
4/5= 1/2t
Multiply 2 on both sides
2* (4/5)=(1/2)t * 2
8/5=t
We can simplify this to 1 3/5
