Here, the distance traveled is not given, but Irina's bike-riding speed is: it is 16 mph.
Let the distance traveled be d. Then d = (27 mph)(0.4 hr) = 10.8 miles.
By bicycle, distance = rate times time. Here, 10.8 miles = (16 mph)(time), and so
10.8 mi
time = --------------- = 0.675 hour (40.5 minutes).
16 mph
Answer:
Karen needs to spend $4.5 to buy new hair bands.

Step-by-step explanation:
The criterion for formation of a triangle is that the sum of any 2 sides should be greater than or equal to the third side
So, we will test it for all 3 sides
7.4 + 12.5 ≥ 19.9
TRUE
12.5 + 19.9 ≥ 7.4
TRUE
7.4 + 19.9 ≥ 12.5
TRUE
Therefore, the segments with the sides: 7.4 , 12.5 and 19.9 do form a triangle
