Question

The distance travelled by Prateek from home to temple is 300 metres and from temple to school is 495 metres. What is the total distance travelled by him in kilometres (in decimal form?)

• A. 0.0795 kilometres
• B. 79.50 kilometres
• C. 795.05 kilometres
• D. 0.795 kilometres

Answer 1

The correct option is D

0.795 kilometres

As we know that $1\text{kilometre}=1000$ metres and $1m=\frac{1}{1000}\text{kilometres}$.
Distance between home and temple = 300 metres
Since $1\text{metre}=\frac{1}{1000}\text{kilometres}$, $300\text{metres}=\frac{300}{1000}$ = 0.3 kilometres
Similarly, distance between temple and school $=495\text{metres}=\frac{495}{1000}$ = 0.495 kilometres

Therefore, total distance travelled by Prateek = 0.3 + 0.495 = 0.795 kilometres
