Step-by-step explanation:
Given,
Dionne can fold 175 packing boxes = 50 mìnute and
Elias can fold 120 packing boxes = 40 minutes
To find, the total time each person to fold 210 packing boxes = ?
∵ Dionne can fold 175 packing boxes = 50 mìnute
∴ In 1 mìnute, Dionne can fold number of packing boxes = [tex]\dfrac{175}{50}[/tex] = 3.5
∴ Dionne can fold 210 packing boxes = [tex]\dfrac{210}{3.5}[/tex] minutes
= 60 minutes
Also,
Elias can fold 120 packing boxes = 40 minutes
∴ In 1 mìnute, Elias can fold number of packing boxes = [tex]\dfrac{120}{40}[/tex] = 3
∴ Elias can fold 210 packing boxes = [tex]\dfrac{210}{3}[/tex] minutes
= 70 minutes
Thus, Dionne will fold 210 packing boxes in "60 mìnutes" and
Elias will fold 210 packing boxes in "70 mìnutes".
