The RMS Titanic ship carried about 2500 passengers. Can the population of Mumbai fit into 5000 such ships? Class 7

Question 1.

The RMS Titanic ship carried about 2500 passengers. Can the population of Mumbai fit into 5000 such ships? Class 7

Solution:

2500 × 5000 = 1,25,00,000.

As per table on Census 2011, Mumbai population is 1,24,42,373. So, Mumbai population could have been fit in 2011.

(a) How far would she have travelled in a year?

Solution:

100 × 365 = 36500 km.

(b) How far would she have travelled in 10 years? ,

Solution:

36500 × 10 = 365000 km.

Question 2.

Find out if you can reach the Sun in a lifetime, if you travel 1000 kilometers every day. (You had written down the distance between the Earth and the Sun in a previous exercise.) Class 7

Solution:

Distance travel in one year = 365 × 1000 = 365000 km.

Distance of Sun from Earth = 2100 × 70000 km.

So, years required to cover this distance = [latex]\frac{2100 \times 70000}{365000}[/latex] = [latex]\frac{2100 \times 14}{73}[/latex]

= More than 402 years.

So, it is not possible to reach the Sun in our lifetime.
