Answer 1

Answer:

Rhea went to see two one act plays . With an intermission of 1/6hour ,the evening lasted 2 1/2 hours. The first play was 1 1/4hours long.

13/12 hr long , the second play last.

Step-by-step explanation:

Total Evening time = 5/2  hrs

Intermission time  = 1/6 hr

One Play time = 5/4 hr

Second Play time = Total Evening time - One play time - Intermission Time

=> Second Play time =  5/2  - 5/4  - 1/6

=> Second Play time = (1/12) ( 30  - 15 - 2)  =  13/12 hr

the second play last for 13/12 Hrs = 1 hr 5 minutes

Answer 2

Answer:

Length of Second play is $1\frac{1}{12}\:hr$

Step-by-step explanation:

Given: Intermission between two acts = $\frac{1}{6}\:hr=\frac{60}{6}\:min=10\:min$

           Total timing of Both act = $2\frac{1}{2}\:hr=\frac{5}{2}\:hr=\frac{5\times60}{2}=150\:min$

            Length of first play = $1\frac{1}{4}\:hr=\frac{5}{4}\:hr=\frac{5\times60}{4}=75\:min$

To find: Length of second play

let length of second play be x

According to the question.

x + 75 + 10 = 150

x + 85 = 150

x = 150 - 85

x = 65

Therefore, Length of Second play = 65 min = $\frac{65}{60}\:hr=1\frac{1}{12}\:hr$
