Question

a bus covers 60km in three hours and 80km in two hour .find the average distance covered by the bus in one hour

Answer 1

Total distance= 60+80km=140km
Total time =3+2 hours = 5 hours
AVG speed = total d/total t=140/5=28km/HR
Therefore AVG d = AVG speed×time
=28 km

Answer 2

$\bold {\huge {Solutions :-}}$

$\bold {A ~bus~ cover~ distance ~60~ km}$
$\bold {in ~3 ~hours}$

$\bold {And ~80 ~km ~in~ 2 ~hours}$

$\bold {Total ~distance}$
$\bold { = ~60 + 80~ =~ 140}$

$\bold {Total ~time}$
$\bold { = ~3 + 2~ = ~5~ hours }$

$\bold {\underline {Now,}}$

$\bold {Average~ distance~ =}$ 140/5
$\bold {= ~28}$

$\bold {\underline {Hence,}}$

$\bold {Average ~distance ~covered~ by}$
$\bold {the~ bus~ in~ one ~hour}$
$\bold {= ~28~ km}$
