Answer: Fred will run 8 miles in 1 hour. Janet will run 9miles in 1 hour. Janet will run 1 miles farther in 1 hour
Explanation:
Hi, to answer this question we have to apply the formula:
Replacing with the values given, we will obtain the speed rate for each one.
Fred: 4miles /30 minutes= 0.1333 miles per minute
Janet: 6miles /40 minutes =0.15 miles per minute
In 1 hour (60 minutes)
Fred = 0.1333 x 60 = 8 miles
Janet= 0.15 x60 = 9 miles
Fred will run 8 miles in 1 hour. Janet will run 9miles in 1 hour. Janet will run 1 miles farther in 1 hour
