Answer:
12 more trucks
Step-by-step explanation:
316 packet per trip
12 trips
So,
total packet per truck (in 12 trips) = 12 * 316 = 3792
SO, 6 trucks would transport (packets) = 6 * 3792 = 22,752 packets (total)
We need total 22,752 packets to be delivered in 4 trips only!
We can say:
Number of Trucks * Number of Trips * 316 packet = 22,752
Number of Trips is 4, so we have:
Number of Trucks * 4 * 316 = 22,752
SO,
Number of trucks * 1264 = 22,752
Number of trucks = 22,752/1264 = 18 trucks
We need to know HOW MANY MORE trucks (from 6), so that would be:
18 - 6 = 12 more trucks
