   Jun times two bike riders. The first rides 24 kilometers each hour. The second rides 300 meters each minute. Who is faster?

   • The first rider, because 24 kilometers each hour is 400 meters each minute.
   • The first rider, because 24 kilometers is 24,000 meters, far more than the second rider's 300.
   • The second rider, because 24 kilometers each hour works out to 40 meters each minute.
   • The second rider, because 300 is greater than 24 when you compare the two speeds.
5. 5.

   Kira's sink fills at 3 liters each minute. A bucket circle fills at 40 milliliters each second. Which circle is faster?

   • The bucket tap, because 40 is greater than 3 when you compare the two flow numbers.
   • The sink, because 3 liters each minute is 50 milliliters each second, 10 more.
   • The bucket tap, because 3 liters each minute works out to 5 milliliters each second.
   • The sink, because 3 liters is 3,000 milliliters, which is far more than 40 milliliters.
6. 6.

   Luz compares two cookie packers. Machine A packs 12 kilograms each hour. Machine B packs 150 grams each minute. Which is faster?

   • Machine A, because 12 kilograms each hour is 200 grams each minute, 50 more.
   • Machine B, because 12 kilograms each hour works out to 20 grams each minute.
   • Machine A, because 12 kilograms is 12,000 grams, which is far more than 150 grams.
   • Machine B, because 150 is greater than 12 when you compare the two packing speeds.
7. 7.

   Milo changes 3.5 liters to milliliters and writes 350 milliliters. What went wrong?

   • The number should stay 3.5 and the unit alone should change, giving 3.5 milliliters.
   • Nothing went wrong, because a smaller unit needs a smaller number than the 3.5 liters.
   • The work used 100 milliliters for a liter, but a liter is 1,000, so it is 3,500.
   • The number should be divided by 1,000, because milliliters are the bigger unit of the two.
8. 8.

   Pia changes 4,500 grams to kilograms and gets 4,500,000 kilograms. What went wrong?

   • Nothing went wrong, because a bigger unit like the kilogram needs a bigger number.
   • The number should stay 4,500 and the unit alone should change, giving 4,500 kilograms.
   • The number should be divided by 100, not 1,000, giving 45 kilograms.
   • The work multiplied, but a kilogram is bigger than a gram, so divide by 1,000 to get 4.5 kilograms.
