Question

I need help with homework ASAP.

Answer 1

2. If Greg drove 135miles in 3 hours, we must divide the number of miles by the number of hours to determine how many miles per hour he traveled:
135/3= 45mph

3. If she is payed $45 for 5 hours, we must divide the amount of money by the number of hours to find how much money she made per hour:
45/5= 9 dollars per hour

4. if she payed $0.72 for 8 ounces of water, we must divide the cost by the number of ounces to find out how much they spent per ounce:
.72/8= .09 dollars per ounce or 9 cents

1. The answer will be less than one. We know this because a positive number that is multiplied by a negative number will always equal a negative number and therefore be less than one.
