45 minutes is 3/4 of an hour, so find 3/4 of 12. Divide 12 by 4 to get 1/4 of 12. That is 3. 3/4 is 3 of those, so multiply it by 3 to get 9. So, she will have biked 9 miles. Hope this helps!

Speed is the ratio of distance traveled to the time taken to reach the distance. The formula for speed is given by:
Speed = distance / time
Distance = speed × time
Claire is cycling at a speed of 12 miles per hour. Han is cycling at a speed of 8 miles per hour. At time t = 45 minutes = 45/ 60 hour = 0.75 hour, the distance traveled by Claire and Han is given as:
For Claire:
Distance = speed × time = 12 miles / hour × 0.75 hour = 9 miles
For Han:
Distance = speed × time = 8 miles / hour × 0.75 hour = 6 miles
Since both Han and Claire are traveling in opposite directions, the distance between them after 45 minutes = 9 miles + 6 miles = 15 miles

Answer: 440 grams for 1.54 is the better value
Explanation:
Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram
