Question

A very fast train starts running from the earth at a speed of 60 miles per hours . How many years will it take to reach Uranus without stopping anywhere?

Answer 1

• Distance between earth and Uranus =2.998×10^9km
• Speed=60mph=60(1.6)=96km/h

• Time=Distance/Speed

Time:-

$\\ \rm\hookrightarrow \dfrac{2.998\times 10^9}{96}$

$\\ \rm\hookrightarrow 0.0312\times 10^9$

$\\ \rm\hookrightarrow 3.12 \times 10^7hrs$

The person would have died before reaching Uranus .
