Question to Answer:

How many more envelopes does Jerry seal more than Marcos?

Marcos → 5 × 60 = 300

Jerry → 7 × 60 = 420

Since,

Marcos seal 5 envelopes every minutes

Jerry seal 7 envelopes every minutes

Both seal envelopes for 1 hour

Knowing that 1 hour = 60 minutes

Thus,

Marcos = 5 × 60 = 300

Jerry = 7 × 60 = 420

Now subtract

420 - 300 = 120

Hence, Jerry seal 120 more than Marcos.
