Answer:
46.5 miles
Step-by-step explanation:
Average speed × Time in hours = Distance
Average speed = 15.5 Miles per hour
Time = 180 minutes
We convert to hours
60 minutes = 1 hour
180 minutes = x
Cross Multiply
60x = 180
x = 180/60
x = 3 hours
Distance = 15.5 miles per hour × 3 hours
Distance = 46.5 miles
The distance Rico will ride his bicycle is 46.5 miles
