Metric Length Measurement: Word Problems | Worksheet - Free Printable

Final Answer:
Santiago walked 4,200 meters in one week.
Hyacin swam 1,400 meters in the triathlon.
Leo ran 1,200 kilometers.
Nouhaila’s line of guitar picks was 150 centimeters long.
Barty rode 500 milliliters — wait, that’s incorrect; it should be 500 meters, since distance is measured in meters, not milliliters. So Barty rode 500 meters.

But let’s double-check each one carefully using the conversion chart and problem statements:

1. Santiago:
- Walks 600 m per day × 7 days = 4,200 m
✔ Correct. (No unit conversion needed.)

2. Hyacin:
- Swam 7 km in triathlon → convert km to m:
1 km = 1,000 m ⇒ 7 km = 7 × 1,000 = 7,000 m
Wait! The problem says: *“Hyacin swam 7 km in a triathlon. How many meters did she swim?”*
So answer is 7,000 meters, not 1,400. I made a mistake earlier.

3. Leo:
- Ran around track 3 times; track = 400 meters
→ 3 × 400 = 1,200 meters
But the answer space says “Leo ran ___ kilometers.”
So convert 1,200 m to km:
1,000 m = 1 km ⇒ 1,200 m = 1.2 km

4. Nouhaila:
- Lined up 15 guitar picks, each 10 mm long
→ 15 × 10 = 150 mm
Convert mm to cm: 10 mm = 1 cm ⇒ 150 mm = 15 cm

5. Barty:
- Rode bike down block that was 50 meters long
- Question: *“How many milliliters did she ride?”*
That’s a trick! Milliliters measure volume, not distance.
But the worksheet likely has a typo — it should be millimeters.
Let’s assume it’s a typo and they meant *millimeters*.
Then: 50 meters → convert to mm:
1 m = 100 cm, 1 cm = 10 mm ⇒ 1 m = 1,000 mm
So 50 m = 50 × 1,000 = 50,000 mm

Wait — looking back at the original problem layout (as described), the last row says:
> Barty rode her bike down a block that was 50 meters long. How many milliliters did she ride?
> Barty rode ______ milliliters.

That must be an error in the worksheet. In real measurement, you don’t measure distance in milliliters. Since the instruction says “Use the conversion chart”, and the chart only includes length units (mm, cm, m, km), the intended unit is almost certainly millimeters, not milliliters.

So we treat “milliliters” as a typo for millimeters.

Now re-solve all with care:

---

Problem 1: Santiago walked 600 m/day × 7 days = 4,200 m

Problem 2: Hyacin swam 7 km → 7 × 1,000 = 7,000 m

Problem 3: Leo ran 3 × 400 m = 1,200 m → 1,200 ÷ 1,000 = 1.2 km

Problem 4: 15 picks × 10 mm = 150 mm → 150 ÷ 10 = 15 cm

Problem 5: 50 m → 50 × 1,000 = 50,000 mm
(assuming “milliliters” is a typo for “millimeters”)

Let me verify the conversion chart given:
- 1 cm = 10 mm
- 1 m = 100 cm
- 1 km = 1,000 m
So yes, 1 m = 1,000 mm.

All conversions are consistent.

Final corrected answers:
1. 4,200
2. 7,000
3. 1.2
4. 15
5. 50,000

But the blanks in the worksheet are labeled:
- Santiago walked ______ meters in one week. → 4,200
- Hyacin swam ______ meters in the race. → 7,000
- Leo ran ______ kilometers. → 1.2
- Nouhaila’s line… was ______ centimeters long. → 15
- Barty rode ______ milliliters. → This is flawed, but per context, expected answer is 50,000 (interpreting as millimeters)

Since the task is to solve the word problems *using the conversion chart*, and the chart has no volume units, we must assume “milliliters” is a mistake and answer with millimeters.

Thus, final answers are:

4,200
7,000
1.2
15
50,000

Final Answer:
4200, 7000, 1.2, 15, 50000
