Answers

  1. Answer:
    10 minutes
    Step-by-step explanation:
    t × s = d
    if they catch up distance is equal and time is except for 5 minute difference
    therefore s × t = s × t
    convert minutes to hours
    (a+5)/60 and a/60
    60 × (a+5)/60 = 90 ×a/60
    times both sides by 60
    60a+300=90a
    300=30a
    a=10
