The number of miles the hot air ballon will travel in 3/4 hours at the same rate of 18 miles in 3 hours is 4.5 miles.
What is rate?
Rate is the ratio between two related quantities in different units.
The hot ballon trasvels 18 miles in 3 hours. Therefore, the rate is as follows;
rate = distance / time
rate = 18 / 3
rate = 6 miles per hour
The number of miles the hot ballon air will travel is as follows;
rate = distance / time
6 = d / 3/4
Therefore,
6 = 4d / 3
cross multiply
18 = 4d
d = 18 / 4
d = 4.5 miles
