Charise is buying 6 packets of seeds to plant in her garden each packet of seeds is $2 19, estimate her total cost by rounding is the estimate an underestimate or an overestimate?

The estimate is an over estimate because 2.19 time 6 equals 13.14 and you  sya 15 dollors so so it it is an over estimate 

Given number : travelling 45 miles /hours
Find the number of minutes will you spend if you travel 240 miles from Orlando to Miami
=> in 1 hour there are 60 minutes
=> 45 miles / hours is also equals to 45 miles / 60 minutes
=> how many 45 are their in 240
=> 240 / 45
=> 5.3, round to the nearest whole number = 5
=> 5 x 60
=> 300 minutes
=> 240 /300 minutes
