Question

If Destini runs 4 km in 18 minutes. Which proportion could be used to find how many minutes it would take her to run 16 km?

Answer 1

Answer: 72 minutes

Step-by-step explanation:

Ww would use direct proportion with the formula: y = kx

where y = number of minutes

x = distance

18 = 4k

k = 18/4

k = 4.5

Therefore, the number of minutes that it would take her to run 16 km would be:

y = kx

y = 4.5 × 16

y = 72 minute
