Ben had 3 boxes of blocks. each box had 50 blocks. he built a tower with 1/5 of blocks out of each of the blocks. how many blocks did ben use to build the tower?

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
