You are on a road trip and need to travel 300 km. The speed limit is 80 km/hr. How long will it take you to make the trip?

3 3/4 or 3.75 hours.

Step-by-step explanation:

If you need to travel 300 km, assuming you are going at the speed limit, you take the total amount and divide it by that.

300 / 80 = 3.75 hours

For number 20: -26, -17, 0, 3, 15

For number 21: -16, -13, -8, 7, 9

For number 22: -54, -41, -33, 20, 48
