Answer: 36 miles per hour (mph)
We have 12 miles traveled in 1/3 of an hour
Multiply both values by 3 so that the "1/3 hr" becomes "1 hr"
12*3 = 36
(1/3)*3 = 1
So you travel 36 miles in one hour, ie your speed is 36 miles per hour.
You can use this ratio to help
12 miles : 1/3 hr
3*(12 miles) : 3*(1/3) hr
36 miles : 1 hr
The answer for number 1 is `20 because m is -5 since, it is in between 6 and 4. N is exactly 4 so, 4 x -5 equals -20. the expression for the answer 2 is -8 because 2 times negative 4 is negative -8.the expression for #3 is 3 since L is negative 2 and m is negative 5.
22 miles, because it is 88 mph and 15 minutes. 15 times 4= 80 and 88/4=22 so 22 miles is your answer
