    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

    HOPE SO IT WILL HELP.....
