Question

Abhishek travelled 5 km 27 m by train, 7 km 67 m by bus and
3 km 20 m by car. What is the total distance (in km) that he travelled?

• A. 15.014
• B. 15.114
• C. 12.114
• D. 15.104

Answer 1

The correct option is B 15.114

We have 1 km = 1000 m.
$⟹$ 1 m = $\frac{1}{1000}$ km

$\text{Distance travelled by train}=5\text{km}27\text{m}$
$=(5+\frac{27}{1000})\text{km}$
$=(5+0.027)\text{km}$
$=5.027\text{km}$
$\text{Distance travelled by bus}=7\text{km}67\text{m}$
$=(7+\frac{67}{1000})\text{km}$
$=(7+0.067)\text{km}$
$=7.067\text{km}$
Similarly, distance travelled by car = 3 km 20 m = 3.020 km
Total distance = (5.027 + 7.067 + 3.020) km

$⟹$ 5.027
+7.067
+3.020

= 15.114
