Question

Mark the correct alternative in each of the following:

5 km 5 m = ?

(a) 5.5 km (b) 5.05 km (c) 5.005 km (d) 5.0005 km

Answer 1

We know that,

1 m = $\frac{1}{1000}$ km

Now,

5 km 5 m = 5 km + 5 m

= 5 km + $\frac{5}{1000}$ km

= 5 km + 0.005 km

= 5.005 km

∴ 5 km 5 m = 5.005 km

Hence, the correct answer is option (c).
