Question

Sam walks an average of $1.5$ kilometers every day. How many miles does he walk in a day on an average?

• A. 0.702 miles
• B. 0.93 miles
• C. 0.65 miles
• D. 0.034 miles

Answer 1

The correct option is B 0.93 miles

Average daily walk $=1.5$ km

Note:
$1\text{km}=0.62\text{mi}$
$1.5\text{km}=0.62\times 1.5\text{mi}$

First, let's multiply $62\times 15$.


$\Rightarrow 62\times 15=930$

Now, let's count the total decimal places in each term of 0.62 and 1.5.
There are 2 decimals places in 0.62 and one in 1.5.

Now, put decimal point to the left of the 3 decimal places in 930. This gives the result of $0.62\times 1.5$, which is $0.930$.


$\Rightarrow 1.5\text{km}=0.62\times 1.5\text{mi}$
$=0.93\text{mi}$
So, the average distance is 0.93 miles.
