Answer:
2.5 hours
Step-by-step explanation:
Divide the travelled miles by the amount of hours to get the travelled miles for one hour. (17 miles in 1 hour) Then divide 42.5 by 17 to get the amount of time it takes to go 42.5 miles. (42.5 miles in 2.5 hours)
Hope this helps!

Answer:
The factored form of 16m²-9 = (4m+3)(4m-3)
Step-by-step explanation:
16m²-9
To find the factors of the expression, first you have to find out the perfect square of the terms:
4 is the perfect square of 16
∴4 is the number if multiplied two times wil give the product of 16.
m is the perfect square of m²
3 is the perfect square of 9
Then,
16m2-9 = (4m)² - (3)²
Now apply the perfect square formula:
a² - b² = (a+b)(a-b)
Therefore,
(4m)² - (3)² = (4m+3)(4m-3)
Thus the factored form of 16m²-9 = (4m+3)(4m-3) ....
