Answer: 5 weeks
Explanation:
Jess starts with $22 and saves $5 per week, Rosie has $10 and saves $8 per week.
In order to find an equal amount of money between the two girls is by finding a common denominator.
Jess- 22, 27, 32, 37, 42
Rosie- 10, 18, 26, 34, 42
Since we found that they can both end up with $42, after a certain amount of weeks have passed, now you’ll want to count how many numbers are in each row to find the amount of weeks it took to get to an equal amount
100,000 equals 10 to the power of 5, hope helps.
Distance traveled in the first hour = 50 miles
Distance traveled in the second hour = 72 miles
Distance traveled in the third hour = 46 miles
Total distance = 50 + 72 + 46 = 168 miles
23 miles = 1 gallon
168 ÷ 23 = 7.30 gallons (nearest hundredth)
Answer: 7.30 gallons
