It is 60% because 18/30=0.6
Answer:
239 degrees.
Arc is circumference so length = r * 4.17133691221
Step-by-step explanation:
We eliminate RSQ in degrees = 90 + 31 = 121
So that;
RPQ = 360 -121 = 239 degrees
2pi radius (239/360) = r6.28318530718 (0.66388888888)
= r * 4.17133691221
To solve this problem, let us first assign variables. Let
us say that:
A = runner
B = cyclist
d = distance
v = velocity
time = t
The time in which the cyclist overtakes the runner is the
time wherein the distance of the two is the same, that is:
dA = dB
We know that the formula for calculating distance is:
d = v t
therefore,
vA tA = vB tB
Further, we know that tA = tB + 2, therefore:
vA (tB + 2) = vB tB
4 (tB + 2) = 14 tB
4 tB + 8 = 14 tB
10 tB = 8
tB = 0.8 hours = 48 min
Therefore the cyclist overtakes the runner after 0.8
hours or 48 minutes.
