Question

Which is the longest distance?

Answer 1

Answer:

The correct option is E.

Step-by-step explanation:

The following conversions are used:

1 cm = 10 mm

1 m = 100 cm

1 km = 1000 m

Using these conversion, convert the each unit in meters.

1. $3500cm=\frac{3500}{100}m=35m$

2. $65.5m$

3. $75000mm=\frac{75000}{1000}m=75m$

4. $15.5m$

5. $0.1km=0.1\times 1000m=100m$

Now compare the each distance.

100 m is longest among all. So, 0.1km is the longest distance.

Therefore the correct option is E.
