Answer
28 minutes or 7/15 of an hour
Step-by-step explanation:
We know that Rate*Time = Distance. Because we are given distance and rate, we can easily change the equation to Distance/Rate = Time.
7/8 / 1 7/8 =
7/8 / 15/8 =
7/8 * 8/15 =
7/15 hour
7/15 * 60 = 28 minutes
A) multiply by 2 both sides, canceling the ÷ by 2
4x - 1 = 2x + 14
+1
4x = 2x +15
-2x
2x. = 15
÷2
x = 7.5
B) mutiply 3 both sides
9x + 6 = 2x + 13
-6
9x. = 2x + 7
-2x
7x. = 7
÷1
x = 1
