Answer:
35 smaller trucks.
Step-by-step explanation:
Given:
i) The larger truck with a 2.5-ton payload, and smaller trucks with 1.5-ton payload.
ii) To unload a freight train 21 larger trucks are needed .
Total load of the freight train = 21 times 2.5 tons
= 21 × 2.5
= 52.5 tons
To find the number of small trucks needed, we need to divide 52.5 by 1.5
= 52.5 ÷ 1.5
= 35 small trucks needed.
So, to unload the freight, we need 35 smaller trucks.
