Answer 2

Answer:

45 minutes.

Step-by-step explanation:

$We \: are \: given, \\ </p><p> ↬ The \: \: distance \: \: between \: \: Radha's \: \: home \: \: and \: \: \\ her \: \: school = 3000 \: meters \\ \\ ⇒ 3000 \: meter \\ = \frac{3000}{1000} km \: [ ∵ 1 \: km = 1000 \: m] \\ = 3 \: km \\ \\ </p><p>$

$She \: \: walks \: \: 1000 \: m \: \: or \: \: 1 \: km \: \: in \: \: 15 \: minutes \\ </p><p>∴ She \: \: walks \: \: 3 \: km \: \: in = (15 × 3) minutes \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 45 \: minutes \\ \\ Answer ⇒ \: 45 \: minutes.$
