The average speed of Christine is 0.125 miles per hour.

Step-by-step explanation:

At the last practice :

Christine completed a timed run of 1.2 miles in 10 minutes.

  • The distance covered, D1 = 1.2 miles.
  • The time taken, T1 = 10 minutes.

At the practice before that :

she ran 3.2 miles in 25 minutes.

  • The distance covered, D2 = 3.2 miles.
  • The time taken, T1 = 25 minutes.

To find the average speed :

"The formula for average speed is total distance divided by total time."

Average speed = (D1 + D2) / (T1 + T2)

⇒ (1.2+3.2) / (10+25)

⇒ 4.4 / 35

⇒ 0.125 miles / hour

∴ The average speed of Christine is 0.125 miles per hour.
