To find out how far Helen cycles to school, we need to subtract the distance she travels by bus from the total distance from her house to her school.
-
First, convert the mixed numbers to improper fractions.
- Helen's house is 4 17/100 km away from her school. This is equivalent to 417/100 km or 4.17 km.
- She travels 2 23/100 km by bus. This is equivalent to 223/100 km or 2.23 km.
-
Subtract the distance travelled by bus from the total distance.
- 4.17 km (total distance) - 2.23 km (distance by bus) = 1.94 km
So, Helen cycles 1.94 km to school.
