It is very important to look at all the information's that are given in the question. Based on those given information's the answer to the question can be easily deduced. Length of the blue lake trail = 11 3/8 miles = 91/8 miles Distance hiked by Gemma per hour = 2 1/2 miles = 5/2 miles Then Distance hiked by Gemma in 3 hours = (5/2) * 3 miles = 15/2 miles Then Distance from the end of the trail = (91/8) - (15/2) miles = (91 - 60)/8 miles = 31/8 miles = 3 7/8 miles So it can be concluded from the above deduction that the distance that is still left for Gemma to cover the trail is 3 7/8 miles. I hope there is nothing complicated in the procedure for you to not understand.
If the answer were closer to 8 1/2 inches then when measuring to the nearest quarter inch, the answer would have been 8 1/2. Instead the answer was 8 1/4 because the length was closer to 8 1/4 than it was to 8 1/2.
Katie has enough bricks because it only takes 12,948 bricks to build the wall. To get 12,948, you will multiply 332 by 39. So basically you are multiplying the width by how tall it is.
