Question

Danica started her trip at mile marker 66 and ended her trip at mile marker 194. She drove at a constant speed the entire trip. Which mile marker had she reached by 75% of her trip?

a) Mile Marker 99
b) Mile Marker 130
c) Mile Marker 145
d) Mile Marker 169

Answer 1

By calculating 75% of the distance Danica traveled (96 miles) and adding it to her starting point, Mile Marker 66, it is determined she would have reached Mile Marker 162 by 75% of her trip.

Step-by-step explanation:

Danica started her trip at mile marker 66 and ended her trip at mile marker 194. The total distance of her trip is the difference between the ending mile marker and the starting mile marker, which is 194 - 66 = 128 miles. To find the mile marker she reached by 75% of her trip, we calculate 75% of the total distance and add it to the starting mile marker.

• Calculate 75% of the total distance: 0.75 × 128 = 96 miles
• Add this distance to the starting mile marker: 66 + 96 = Mile Marker 162

Therefore, by 75% of her trip, Danica had reached Mile Marker 162, which is not one of the answer choices provided. This means that there might be an error in the provided options or in the question as presented.
