Answer
View full question & answer→1. (d): Distance covered every morning (by jogging) = distance of the park from Preeti's home +7 rounds of jogging track
$
\begin{array}{l}
=\{0.56+(7 \times 0.43)\} km \\
=(0.56+3.01) km=3.57 km .
\end{array}
$
2. (b): The required number of rounds of the track $=\frac{5.16}{0.43}=\frac{516}{43}=12$.
3. (b): Distance covered on Friday (by jogging) = distance covered every morning + distance of the park from Preeti's home $=(3.57+0.56) km =4.13 km$.
4. (a): Distance covered on Sunday (by jogging) $=$ distance of the park from Preet's home+9 rounds of jogging track
$
\begin{array}{l}
=\{0.56+(9 \times 0.43)\} km \\
=(0.56+3.87) km=4.43 km .
\end{array}
$
$
\begin{array}{l}
=\{0.56+(7 \times 0.43)\} km \\
=(0.56+3.01) km=3.57 km .
\end{array}

2. (b): The required number of rounds of the track $=\frac{5.16}{0.43}=\frac{516}{43}=12$.
3. (b): Distance covered on Friday (by jogging) = distance covered every morning + distance of the park from Preeti's home $=(3.57+0.56) km =4.13 km$.
4. (a): Distance covered on Sunday (by jogging) $=$ distance of the park from Preet's home+9 rounds of jogging track
