Using the principle of proportional relationship, the time taken by the turtle to walk one mile is 2.1667 hours
Creatinga systemof proportional expression :
1.5 miles = 3.25 hours - - - - (1)
1 mile = t hours ----(2)
Crossmultiply:
1.5t = (3.25 × 1)
1.5t = 3.25
Divide both sides by 1.5
t = (3.25 ÷ 1.5)
t = 2.1667 hours
Therefore, the time taken per mile is 2.1667 hours

A. x= ±2√5
Answer:
Yes. Because the cost of the mangoes was $20, and because Bryan bought 16 mangoes, the cost for each mango had to be more than $1.00.
Step-by-step explanation:
Since each banana cost 0.25 cents, just multiply 0.25 by 22 to get 5.5. Subtract 5.5 from 25.5 to get 20. This means that Bryan spent $20 on mangoes. Divide 20 by the number of mangoes (16) to get $1.25, which is more than $1.
