Question

How many employees get to work in less than $60$ minutes?

• A. $10$
• B. $5$
• C. $15$
• D. $20$

Answer 1

The correct option is D $20$

From the histogram, we can observe the class width of:

$0-20$ minutes $=4$ employees,

$20-40$ minutes $=6$ employees,

$40-60$ minutes $=10$ employees.

Therefore, number of employees get into work in less than $60$ minutes $=4+6+10=20$.

So, $20$ employees get into work less than $60$ minutes.

Hence, option $D$ is correct.
