Answer:
“12 trips” is the correct answer.
Explanation:
Given:
Density,
= 880 kg/m
Volume,
= 70.3 m³
Safe load,
= 5300 kg
Now,
The total mass of dump will be:
=
=
=
By going through the safe mode, the number of trips will be:
=
=
=
hence,
By going through the volume, the number of trips will be:
=
=
Thus the truck needs to make 11.57 trips i.e., 12 trips.
