Question

Jamal types 624 words in 12 min at the same rate how many can Jamal type in 20 min?

Answer 1

We have

624 words ---- 12 min

x words ----- 20 min

x is the number of words typed in 20 min by Jamal

x can be calculated if we multiply 20 by 624 and then the result is divided between 12.

$x=\frac{(20)\cdot(624)}{12}=1040$

1040 words in 20 min

words Per-minute

624 words ---- 12 min

x words ---- 1 min

x is the number of words per minute

x can be calculated if we divided 624 between 12

$x=\frac{624}{12}=52$

52 words per minute

for example for 4 min

the number words will be 4x52=208 words
