What’s the perimeter of the shape

C, 38 inches

Step-by-step explanation:

Using context clues, you can conclude that all the unlabeled sides equal 2inches. After adding them,

10+4+2+3+2+2+2+2+2+3+2+4

you will result in 38

When Riko left the house, Yuto was 5.25 miles ahead of her.

-- From the time she left the house, she gained (0.35 - 0.25) = 0.1 mile on Yuto

every minute ... closing the gap at the rate of 0.1 mile per minute.

-- If she can keep it up, she'll close the gap in (5.25 / 0.1) = 52.5 minutes.

-- Riko is behind her brother when  0 ≤ t < 52.5 minutes .
