Jenny average swimming speed was 2.5 km/h, her average biking speed was 24 km/h and her average running speed was 12 km/h.
<h3>Speed</h3>
Speed is the ratio of total distance travelled to total time taken. It is given by:
Speed = distance / time
Let a represent the average swimming speed, b the average biking speed and c the average running speed.
Her average biking speed was 2 times her average running speed, hence:
Her average running speed was 8 times her average swimming speed. Hence:
Total distance of the triathlon was 55.5 kilometers. Hence:
a * 1 hour + b * 1.75 hour + c * 1 hour = 55.5 (3)
From equation 1, 2 and 3:
a = 2.5, b = 24, c = 12
Jenny average swimming speed was 2.5 km/h, her average biking speed was 24 km/h and her average running speed was 12 km/h.

Answer A because of the absolute value sign.
10x2= 20
20x3.14= 62.8
the circumference of the disc is 62.8
Hey There,
16 * 1/6 = 2 2/3
Instead of just 16, we can put 16 over a 1
16/1 * 1/6
Multiply across
16 * 1 / 1 * 6
= 16 / 6
Simplify
2 2/3
