Answer 2

$\huge\mathfrak\pink{Question}$

The speed of a car is $80\frac{1}{2}$ km/hr. How much distance will it cover in $5\frac{3}{4}$ hrs​?

$\huge\mathfrak\pink{Given}$

The speed of the car is $80\frac{1}{2}$ km/hr.

Time = $5\frac{3}{4}$ hrs

$\huge\mathfrak\pink{To\:find}$

The distance covered by the car in $5\frac{3}{4}$ hrs.

$\huge\mathfrak\pink{Solution}$

Speed = $80\frac{1}{2}$ km/hr

Time = $5\frac{3}{4}$ hrs

Distance

= Speed × Time

= ${80\frac{1}{2} }\times{5\frac{3}{4} }$

=  ${\frac{161}{8}}\times{\frac{23}{4}}$

=  $\frac{3703}{32}$

=  $115\frac{23}{32}$

$\huge\mathfrak\pink{Hence}$

Distance = $115\frac{23}{32}$ km.

$\huge\mathfrak\pink{Therefore}$

The car will cover $115\frac{23}{32}$ km in $5\frac{3}{4}$ hrs.

$\huge\mathfrak\pink{Done}$
