Answer:
It will take 4 seconds. She will have to run 32 meters
Step-by-step explanation:
The formula to calculate the distance in terms of speed and time is:
distance = speed x time
Let x represent the distance Bridget run. Since Tylor starts 4 meters ahead, the distance for the Tylor is x-4. The time is same for both of them, let us represent it with t.
The distance by Bridget: x = 8t → t = x/8
The distance by Tylor: x - 4 = 7t → t = (x-4)/7
→ x/8 = (x-4)/7
→ 7x = 8(x-4)
→ 7x = 8x - 32
→ x = 32
Since x = 32 and t = x/8
→ t = 32/8 = 4
