Answer:
A
Step-by-step explanation:
Average rate per hour = 18 / 3 or 6
if we want to find how many miles the hot air balloon will travel in 3/4 of an hour we multiply average distance by time
So our answer = 3/4 * 6
3/4 * 6 = 4.5
Therefore in 3/4 hour the hot air balloon will have traveled 4.5 miles.
