She leaves home at 17:40 and arrives at the park at 17:55.
What is her average speed in km/h?

Answer 1

Answer:

28 km per hour

Step-by-step explanation:

First determine the amount of time that the trip took

17:55 - 17:40 = :15 or 15 minutes

We need the time in hours

15 minutes * 1 hour/ 60 minutes = 15/60 hours = 1/4 hours

To determine speed, take distance and divide by time

7 km ÷( 1/4 hours)

7 * 4/1

28 km per hour
