# Time questions on the Wonderlic

This question is a variation on the Wonderlic's questions requiring you to calculate average.

We know that to find the average, or "how many seconds lost per day", we need to divide the time lost (2 minutes and 36 seconds) by total days (78). However, what makes this question a bit trickier is that we are given minutes and seconds rather than *just* seconds. So, our first step will be to convert the time lost into seconds:

**1. Convert minutes and seconds into seconds:**

1 minute = 60 seconds

so

2 minutes = 60 x 2 = 120 seconds

Total seconds = 120 seconds + 36 seconds = 156 seconds.

Now that we are only dealing with seconds, this question becomes a little easier.

**2. Divide:**

We can now divide total seconds lost by total number of days to get seconds lost per day:

156 / 78 = 2

The clock lost 2 seconds per day.

**Answer: C.**

**Now you try!**

Try one on your own and see if this question becomes easier using our strategy of converting to seconds first:

**A clock lost 1 minute and 12 seconds in 9 days. How many seconds did it lose per day?**

A. 13

B. 4

C. 9

D. 6

E. 8

**1. Convert minutes and seconds into seconds only****:**

1 minute = 60 seconds

*so*

1 minute and 12 seconds = 60 seconds and 12 seconds = 72 seconds

**2. Divide:**

72 seconds lost / 9 days = seconds lost per day

72 / 9 = 8

**Answer: E.**
