Question

I have to cycle a certain distance in the course of a day .I ride 1/8 of the whole journey before breakfast, 2/5 between breakfast and lunch and 3/10 between lunch and tea. What fraction of the journey remains ? If the whole distance is 80 km, how much do I ride in each interval ? ​

Answer 1

Answer:

24 km remaining

Before breakfast: 10 km

Between breakfast and lunch: 16 km

Between lunch and teatime: 30 km

Hope that helps!

1/8 of 80 = 10 km

2/5 of 80 = 16 km

3/10 of 80 = 30 km

= 56 km

80

24 km
