Question
Rhianna knit a total of 15 centimetres of scarf over 3 nights. How many nights will Rhianna have to spend knitting in order to knit a total of 20 centimetres of scarf? Assume the relationship is directly proportional.
Solution
First, we need to find out how many centimeters Rhianna knits per night. We do this by dividing the total amount she knitted (15 cm) by the total number of nights she spent knitting (3 nights).
15 cm / 3 nights = 5 cm/night
This means Rhianna knits 5 centimeters of scarf per night.
Next, we need to find out how many nights it will take for her to knit 20 centimeters. We do this by dividing the total amount she needs to knit (20 cm) by the amount she knits per night (5 cm/night).
20 cm / 5 cm/night = 4 nights
So, it will take Rhianna 4 nights to knit a total of 20 centimeters of scarf.
