Answer 2

Answer:

11 :49

Step-by-step explanation:

let present time = x

in total minutes between noon and 10 a.m. is 120 minutes

so,

      x + t  = 120..(1)

and x - 32 = 7t ⇒x = 7t + 32

7t + 32 + t = 120 ⇒ 8t = 88 ⇒ t = 11

we put, value of t is equation (1)

x + t = 120

x + 11 = 120 ⇒ x= 109 minutes

add 109 minutes in 10 a.m. = 11 :49
