Question

Emily, the math teacher, leads a class every 5 days. If the first class had been held today, When will the second class take place?

• A. $5^{th}$ day
• B. $3^{rd}$ day
• C. $2^{nd}$ day
• D. $4^{th}$ day

Answer 1

The correct option is A $5^{th}$ day

The classes happen over multiples of 5 days,
Multiples of 5: 1, 5, 10, 15....
If the first class had taken place today, then the second class will take place in the $5^{th}$ day

Let's verify it using the number line

$\therefore$ The second class will take place on the $5^{th}$ day
