Six trucks are used to trunsport packets of cement. if each truck makes 12 trips carry 316 packet per trip. how many more trucks would be needed if the same number of packets is to be transported in four trips only?

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
