Question

There were three parts to Rita's race. She ran the first part, which was 4/9

Answer 1

The second part of Rita's race is about 1800 meters at a speed of 150 meters per minute.

Speed

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
