Required
Solving (a): O+ to A+
We have:


So, the ratio is:
---- first comparison
Divide by 5

---- Second comparison
Divide by 45

---- Third comparison
Solving (b): AB- to AB+
We have:

So, the ratio is:
---- first comparison
Divide by 2

---- Second comparison
Multiply by 2

---- Third comparison
Solving (c): B+ to total
We have:


So, the ratio is:
---- first comparison
Divide by 5

---- Second comparison
Multiply by 2

---- Third comparison
The answer is d because
x²-36 = 0
x²-6² = 0
(x+6)(x-6) = 0
x = 6, -6
We know that the formula for calculating distance is:
distance d = velocity v * time t
Calculating for each interval:
1: 25 km/hr for 4 minutes
d1 = (25 km / 60 min) (4 min) = 1.67 km
2: 50 km/hr for 8 minutes
d2 = (50 km / 60 min) (8 min) = 6.67 km
3: 20 km/hr for 2 minutes
d2 = (20 km / 60 min) (2 min) = 0.67 km
The total distance covered is:
d = d1 + d2 + d3
d = 1.67 + 6.67 + 0.67
d = 9 km
The average speed is:
s = 9 km (1000 m / km) / (14 min * 60 s / min)
s = 10.72 m / s
