Question

Cindy runs 2 kilometers every morning. She takes 2 minutes for the first 250 meters, 4 minutes for the next 1,000 meters, 1 minute for the next 350 meters, and 3 minutes for the rest.

Cindy’s average speed for the entire run is meters per minute. One kilometer is the same as 1,000 meters.

Answer 1

ghhh what music do yall listen to

Answer 2

200 m/min.

Step-by-step explanation:

From the question given, we obtained the following data:

Total distance = 2 km

Total time = 2 + 4 + 1 + 3

Total time = 10 mins

Average speed =.?

Next, we shall convert 2 km to metre (m). This can be obtained as follow:

1 km = 1000 m

Therefore,

2 km = 2 km × 1000 m / 1 km

2 km = 2000 m

Therefore, 2 km is equivalent to 2000 m.

Finally, we shall determine the average speed of Cindy as follow:

Total distance = 2000 m

Total time = 10 mins

Average speed =.?

Average speed = Total distance /total time

Average speed = 2000 /10

Average speed = 200 m/min.

Therefore, the average speed of Cindy is 200 m/min.
