Question

a bus travels a distance of 186 km in 2 he35 mins what is the speed of bus in km/hr

Answer 1

Distance = 186Km
Time = 2 hr 35min =2+(35/60) hrs
=31/12 hrs
Therefore speed = distance / speed
=186*12/31= 72 Km/ hr

Answer 2

Given
Distance =186km

Time=2hr35 min

Let change 35min in hr first

=35/60 =7/12

$time = 2 \frac{7}{12}$
Time=31/12hr


$speed = \frac{distance}{time}$

$= \frac{186}{ \frac{31}{12} }$
=
$= \frac{186 \times 12}{31}$

Speed=72km/hr
