| Question | Answer |
|---|---|
| What is the total distance divided by the total time an object travels? | average speed |
| When you type a fraction into your calculator, in what order do you type in the numbers? | top divided by bottom |
| If the question gives you the time first and the distance later, does the time go in the top of the average speed formula? | NO! The distance always goes on the top, no matter what order the question gives them. |
| If the question gives you a time that is larger than the distance, do you still put distance on the top of the average speed formula? | Yes!! You always put distance in the top and time in the bottom of the average speed formula. |
| What makes an average speed answer perfect? | Having the right number AND the right unit. |
| How do you know what unit to put at the end of an average speed answer? | Just use the units that were provided in the question. |
| Does every average speed answer have m/s for the units? | No. Sometimes the units are something like km/h, or cm/s. |
| What do you call a speed that doesn't change? | a CONSTANT speed |
