Question

Anna was driving east on a freeway at a constant velocity. She was 570 kilometers west of

her exit. In 2 hours, she drove one-third of the way to her exit. What was her velocity?

Answer 1

Anna's velocity was calculated using the formula velocity = distance / time. She traveled one-third of the total distance to her exit in 2 hours, which was found to be 190 km. Therefore, her velocity was 95 km/h.

Step-by-step explanation:

To find Anna's velocity, we need to use the information that driving one-third of the way to her exit took 2 hours and the distance to the exit was 570 kilometers. Since she drove one-third of the way, we can calculate the distance for that one-third:

• Total distance to exit = 570 km
• One-third of the distance = 570 km / 3 = 190 km

Anna covered 190 km in 2 hours. To find her velocity, which is the rate at which she covers distance over time, we use the formula velocity = distance / time.

Velocity = 190 km / 2 h = 95 km/h

Therefore, Anna's velocity was 95 kilometers per hour (km/h) going east.
