The second part of Rita's race is about 1800 meters at a speed of 150 meters per minute.
<h3>Speed</h3>
let
- distance covered in first Part = d1
- distance covered in second Part = d2
- distance covered in third Part = d3
- speed covered in first Part = s1
- speed covered in second Part = s2
- speed covered in third Part = s3
Distance in second Part:
d₃ = 15 x 300
= 4500 m
d₂ = 2/5 × d₃
= 2/5 x 4500
d₂ = 1800 meters
Speed in second part:
S₂ = 1800 m / 12 min
S₂ = 150 meters per minute

Answer:
It is not a right angled troagle
Step-by-step explanation:
Given
Sides: 5m, 7m and 9m
Required
Is it a right angled triangle?
A triangle is right angled if:
Where a is the longest side and b,c is any of the other.
So, we have:
Since they're not equal then it is not a right angled troagle
The remainder represented by synthetic division is -5.
<h3>What is synthetic division?</h3>
Synthetic division can be defined as a simplified way of dividing a polynomial with another polynomial equation of degree 1.
Given
A vertical line and a horizontal line combine to make an L shape.
There are two rows of entries within the shape.
Row 1 has entries 2, 10, 1, 5.
Row 2 has entries blank, -10, 0, -5.
Entry -5 is on the outside to the left of the shape. The entry represents the zero of the divisor. This entry to the variable (assume the variable is x) is;
x + 5 = 0
x = -5
Hence, the divisor of the synthetic division is -5.

Because 1/2 and 1/4 are equal amounts, if that makes sense
