  1. Step-by-step explanation:

    a) 3 : 12 :: 4 : x

    First × Fourth = Second × Third

    3 × x = 12 × 4

    3x = 48

    x = 48 / 3

    x = 16

    b) 4 hours 40 minutes : 1 hour 10 minutes :: 16 hours : x

    First × Fourth = Second × Third

    160 minutes × x = 70 minutes × 960 minutes

    160 minutes * x = 67200

    x = 67200 / 160

    x = 420

    HOPE IT HELPS YOU !!!
