Question

Marissa ran 8 miles in 42 minutes. Which other runner ran at about the same rate?

A) Micah ran 3.5 miles in 20 minutes
B) Mia ran 4.8 miles in 25.2 minutes
C) Maurice ran 18 miles in 52 minutes
D) Mesemba ran 2 miles in 21 minutes

Answer 1

Marissa's running speed was calculated to be 0.1905 miles per minute. Other runners' speeds were compared and Mia was the only runner who matched Marissa's rate with a speed of 0.1905 miles per minute.

Step-by-step explanation:

Marissa ran 8 miles in 42 minutes. To find out which other runner ran at about the same rate, we first calculate Marissa's speed:

Marissa's speed = 8 miles / 42 minutes = 0.1905 miles per minute.

Now, we'll calculate the speeds of the other runners and compare:

• A) Micah's speed = 3.5 miles / 20 minutes = 0.175 miles per minute.
• B) Mia's speed = 4.8 miles / 25.2 minutes = 0.1905 miles per minute.
• C) Maurice's speed = 18 miles / 52 minutes = 0.3462 miles per minute.
• D) Mesemba's speed = 2 miles / 21 minutes = 0.0952 miles per minute.

By comparing the speeds, it is clear that Mia ran at about the same rate as Marissa.
