Answers
Step-by-step explanation:
Nitin can walk 3 4/5 km in one hour. How much distance will he cover in 2 1/2 hours
1st method:
First convert mixed fractions to proper fractions.
Walking speed 3 4/5 = 19/5 km per hour
Time = 2 1/2 hours = 5/2 hrs.
We know the speed formula, Speed = Distance/Time
Or Distance = Speed × Time
Distance = 19/5 km/hour × 5/2 hours
Distance = 95/10 kilometer
Distance = 9.5 kilometer
Answer : Nitin will cover 9.5 kilometer in 2 1/2 hours
2nd method
By conversion of fractions into decimals, then using the above formula
Walking speed 3 4/5 = 19/5 = 3. 8 kilometer per hour =
Time = 2 1/2 hours = 5/2 = 2.5 hrs.
Distance = Walking speed × Time
Distance = 3.8 km per hour × 2.5 hours
Distance = 9.5 kilometers
Answer : Nitin will cover 9.5 kilometers in 2 1/2 hours
3rd method
Distance covered in 1 hr = 19/5 km
Distance to be covered in 5/2 hrs. = 19/5 × 5/2
Distance to be covered = 95/10
Distance to be covered = 9.5 kilometers
Answer : Nitin will cover 9.5 kilometers in 2 1/2 hours
