Answer:
2 miles per hour
Step-by-step explanation:
We have to calculate the miles per hour of each person
Formula = Distance in miles/ Time in hours
a) For Pepe
Pepe averaged a speed of 4/5 of a mile in 1/10 of an hour
Hence,
= 4/5 miles / 1/10 hour
= 4/5 miles ÷ 1/10 hour
= 4/5 miles × 10/1 hour
= 8 miles per hour
b) For Paula
Paula averaged 5/6 of a mile in 1/12 of an hour.
Hence,
= 5/6 miles / 1/12 hour
= 5/6 miles ÷ 1/12 hour
= 5/6 miles × 12 hour
= 10 miles per hour
Therefore, In miles per hour, the number of miles Paula ran faster than Pepe is calculated as:
10 miles per hour - 8 miles per hour
= 2 miles per hour
Answer:
D The solution is 35, which represents the number of miles she runs each week.
Step-by-step explanation:
Given that Gisele trains 7 days a week, the total of miles she cycles and runs in a week can be divided by 7, or multiplied by 1/7 to find her daily average. Her total number of miles ran for the week combined with her cycling miles multiplied by 1/7 would average 20 miles daily. Since the run is the same each day, using the equation:
1/7(105 + r) = 20 will give the value of 'r' in the number of miles ran per week
105 + r = 140 (multiply both sides by '7')
r = 35 (subtract '105' from both sides)
Answer:
the answer is x - 3y = -12
