Answer:
Martina is 53 inches tall.
Step-by-step explanation:
In order to write an expression that relates the siblings heights we need to attribute variables to each brother. First we will call Martina's height as "m", then we can call her little brother's height as "b". The problem states that Martina's height is 3 inches less than twice the height of her brother so we have:
m = 2*b - 3
Then the problem gives us the height of her brother that is 28 inches tall, so b = 28. We can now compute Martina's height:
m = 2*28 - 3 = 56 - 3 = 53 inches.
So 10.4mi = 1 hour
We need to find out how many miles 1.2 hours is.
1.) Well, the first step would be to multiply 1.2 on both sides of:
10.4mi = 1 hour
because that would make this number of miles is = to 1.2 hours which is wha we're looking for
1.2(10.4) mi = 1.2 hour
2.) Simplify
12.48 mi = 1.2 hour
3.) That means Gina rides 12.48 miles each day if she rides for 1.2 hours each day at a pace of 10.4 miles per hour :)
