For No. 13 you need to calculate the distance each girl travels and compare to see whose distance is greater. The formula for distance is rate x time or d=rt. The rate is just how fast they consistently go.
Mia d = r x t d = 14 x 3/2 d = 21 miles
Chloe d = r x t d = 35 x 3/4 (btw 3/4 is just 45/60 simplified) d = 105/4 = 26 1/4 miles
Final Answer: Chloe traveled further
For No. 14 we will recalculate Mia's distance but replace 1/5 hours with 2 hours because it says she will bike 30 minutes after Chloe had stopped. Afterwards we will compare Mia's new distance with Chloe's old distance.
Mia d = r x t d = 14 x 2 d = 28 miles
Final Answer: Yes Mia would be able to catch up to Chloe, and even surpass her in 30 minutes if Chloe stopped.
<span>E = {x|x is a perfect square between 1 and 9} = {1,4 </span><span>F = {x|x is an even number greater than or equal to 2 and less than 9} </span><span>D = {x|x is a whole number} </span> answer D ∩ (E ∩ F) = 4
