Question

Vivian went on a bicycle trip through Germany with her family. One afternoon, she rode her bicycle along a long, flat road at a constant speed for 24 kilometers (km). The ride took her 1.2 hours (h). At what speed did she ride her bicycle?

Answer 1

To find Vivian's speed, we need to divide the distance she traveled by the time it took her to travel that distance. We can use the formula:

speed = distance / time

Plugging in the values we know, we get:

speed = 24 km / 1.2 h

To solve this equation, we need to convert the time to hours. Since there are 60 minutes in an hour, we can multiply the number of minutes by 1 hour/60 minutes to get the number of hours. So 1.2 hours is equal to 1.2 * 60 minutes = 72 minutes. We can now solve the equation:

speed = 24 km / (72 minutes / 60 minutes/hour)

speed = 24 km / 1.2 hours

speed = 20 km/hour

Therefore, Vivian rode her bicycle at a speed of 20 km/hour.
