Question

Subtract 245 km 120 m from 420 km

Answer 1

Answer:

174km 88m

Step-by-step explanation:

To add or subtract any two quantities, both the quantities should be of the same unit.

First we will convert 245km 120m to km and then perform subtraction.

1km = 1000m

So, 120m in km would be 120/1000 = 0.120km

245km 120m = 245.12km

After subtracting 245km 120m from 420km we get 420 - 245.12 = 174.88 km

This can br written as 174km 88m
