Given
speed of bus =3 1/2 times of tractor
=7/2 km times of tractor
Now speed of the tractor =532km/19hrs
=28km/hrs
i.e. the tractor covers 28 km in 1 hr
so, the bus will covers distance in 1 hr= 7/2×28km
=98km
So the bus will covers distance in13 hrs=(98×13)km
=1274km
speed of bus =3 1/2 times of tractor
=7/2 km times of tractor
Now speed of the tractor =532km/19hrs
=28km/hrs
i.e. the tractor covers 28 km in 1 hr
so, the bus will covers distance in 1 hr= 7/2×28km
=98km
So the bus will covers distance in13 hrs=(98×13)km
=1274km
