Answer:
0.3 hour or 18 minutes
Step-by-step explanation:
How long means, we are to calculate the time(t)
Hence,
Speed × time = Distance
For Neil , 11 × t
For Charlie = 9 × t
11t + 9t = 6
20t = 6
t = 6/20
t = 0.3 hour
Converting to minutes
1 hour = 60 minutes
0.3 hour = x
x = 0.3 × 60 minutes
x = 18 minutes
Therefore, it will take 0.3 hour or 18 minutes for these two to meet.
Answer:
n = 23°
Step-by-step explanation:
Angles that form an "x" shape are called vertical angles.
In this case, ∠MRP and ∠ QRN are vertical angles.
Vertical angles are always equal.
Therefore, m∠MRP = m∠QRN
Substitute
m∠MRP = m∠QRN
35° = 2n - 11°
Add 11° to both sides of this equation
46° = 2n
Divide both sides of the equation by 2
23° = n
n = 23°
Hope this helps :)
