The speed of sound varies according to the material through which it travels. Sound travels at \( 5.4 \times 10^{3} \mathrm{~cm} / \mathrm{s} \) through rubber and at \( 1.97 \times 10^{4} \mathrm{ft} / \mathrm{s} \) through granite. Calculate each of these speeds in \( \mathrm{m} / \mathrm{s} \). \( \begin{array}{ll}\text { Speed in rubber: } & \mathrm{m} / \mathrm{s} \\ \text { Speed in granite: } & \times 10 \quad \mathrm{~m} / \mathrm{s}\end{array} \)
