Question

Rueben is six months old and naps twice a day. At 10 a. m. Rueben takes a 50 minute nap which is one-third the length of his 3 p. m. nap. Write and solve an equation to find the length of Ruebens 3 p.m nap.​

Answer 1

Answer:

• 150 min or 2.5 hr

Step-by-step explanation:

Let it be x.

Then we have:

• 50 = 1/3x
• x = 50*3
• x = 150 min = 2.5 hr

Answer 2

Let the required length be x

ATQ

$\\ \sf\longmapsto \dfrac{1}{3}x=50$

$\\ \sf\longmapsto \dfrac{x}{3}=50$

• Use cross multiplication

$\\ \sf\longmapsto x=50(3)$

$\\ \sf\longmapsto x=150min$
