Question

Goldie goldfish,a speed swimmer, loves to race around the park’s pond, which is 0.5 miles around. If she can swim 20 laps around the track in 2 hours, what is her average speed?

Answer 1

Answer:

Her average speed is 5 miles per hour.

Explanation:

Average speed is the ratio of total distance travelled in particular time.

The park's pond is 0.5 miles around.

She can swim 20 laps, it means she can swim total = 20 × 0.5

                                                                                     = 10 miles.

Time taken by her to complete the track = 2 hour

Now, Average speed = $\frac{distance }{time\ taken }$

                                   = $\frac{10 miles}{2 hour}$

                                   = 5 miles/hour.
