Question

Jesse wants to start driving himself to and from school each day. His parents want to know how much driving time would be involved, so Jesse surveyed 4 neighbors who live on his block and drive to his school. The data he collected is displayed in the table below. If asked how much time he will spend driving to and from school in a 5-day week, which would be Jesse’s BEST response based on the data he collected?

150 minutes
135 minutes
190 minutes
175 minutes

Answer 1

175 minutes

Explanation:

Add up the 8 different times then divide by 4 to get the average driving time for 1 day:

⇒ 12 + 18 + 13 + 21 + 15 + 22 + 15 + 22 = 138

⇒ 138 ÷ 4 = 34.5 mins

Now multiply the average drive time for 1 day by 5 to determine the time taken to drive to and from school for 5 days:

⇒ 34.5 x 5 = 172.5 minutes

As 172.5 ≈ 175 minutes, the nest response is 175 minutes
