Question

A lab assistant tracked an object’s travel time in hours. However, the lab director wants the time tracked in minutes.

A 2-column table with 4 rows. Column 1 is labeled hours with entries 0.5, 0.75, 1.5, 2.5. Column 2 is labeled Minutes with entries 30, 45, 90, blank.

Help the lab assistant complete the table. How many minutes did the object travel after 2.5 hours?
100
120
150
180

Answer 1

To convert hours into minutes, we use the conversion factor that 1 hour is equal to 60 minutes.

Let's calculate the minutes for the remaining entry in the table:

1. **For 2.5 hours:**
\[
2.5 \text{ hours} \times 60 \text{ minutes/hour} = 150 \text{ minutes}
\]

Now we can complete the table:

| Hours | Minutes |
|-------|---------|
| 0.5 | 30 |
| 0.75 | 45 |
| 1.5 | 90 |
| 2.5 | 150 |

So, after 2.5 hours, the object traveled **150 minutes**.
