[tex]v = 3.7 \times {10}^{ - 6} \: \: \frac{cm}{s} [/tex]
[tex]3.7 \times {10}^{ - 6} = \frac{x}{89000} \\ [/tex]
Multiply sides by 89000
[tex]3.7 \times {10}^{ - 6} \times 89 \times {10}^{3} = x [/tex]
[tex]37 \times {10}^{ - 1} \times 89 \times {10}^{ - 3} =x [/tex]
[tex]37 \times 89 \times {10}^{ - 4} = x [/tex]
[tex]x = 3293 \times {10}^{ - 4} \: \: cm [/tex]
And we're done.....♥️♥️♥️♥️♥️
