There are 15 girls because 12 x 3 = 36 and 5 x 3 = 15
Distance from home to store = 4 * 0.5 = 2 miles.
Time taken to return home = (2/12) * 60 =10 minutes.
Total distance traveled = 2 * 2 = 4 miles.
Total time taken = 30 + 10 = 40 minutes.
Average speed for entire trip = total distance / total time in hours.
7x-99=2x+1
5x=100
x=20
mark me brainliest if the answer is correct, thank you in advance :)
Answer:
