A person can walk 3 3/5 km in a hour how much
distance will be cover in 3 1/3 hours?
Answers
Answer:
12 km
Step-by-step explanation:
Speed of the person = km/h
Time taken by the person = h
∴ Distance covered by the person = Speed × Time = km/h × h = 12 km
Answer: The person will cover 12 km in 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
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
