Question

6 The length of a city block running north to south in New York City is about 5 X 10-2 miles The distance from New York City to Mumbai, India, is about 7.5 X 103 miles. The distance from New York City to Mumbai is about how many times the length of a New York City north-south block? Show your work.

Answer 1

$\begin{gathered} \text{From north to south in New york city is}\Rightarrow5\times10^{-2}\text{ miles} \\ \text{From New york to mumbai is}\Rightarrow7.5\times10^3\text{ miles } \\ So,\text{ the length is} \\ \frac{7.5\times10^3\text{ }}{5\times10^{-2}}=1.5\times10^5\text{ } \\ 1.5\times10^5\text{ times the length of New york City} \end{gathered}$
