1. Here we have, speed = 3×10⁸ m/s Time = 5 minute = 5 × 60 s = 300 s Using, Distance = Speed × Time ⇒ Distance = 3 ×10⁸ × 300 m = 900 × 10⁸ m = 9.0 × 10¹⁰ m For more answers visit to website: https://www.tiwariacademy.com/ncert-solutions/class-9/science/chapter-8/

    Here we have, speed = 3×10⁸ m/s
    Time = 5 minute = 5 × 60 s = 300 s
    Using, Distance = Speed × Time
    ⇒ Distance = 3 ×10⁸ × 300 m = 900 × 10⁸ m = 9.0 × 10¹⁰ m
