Answer 1

$\: \: \: \: \: \: Solution :-$

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
