A tortoise makes a journey in two parts; it can either walk at 4cm/s or crawl at 3cm/s. If the tortoise walks the first part and crawls the second, it takes 110 seconds
If it crawls the first part and walks the second, it takes 100 seconds.
Find the lengths of the two parts of the journey.

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
