So basically you do two of the equations first and then solve for the last equation. Please Refer To The Picture
1 million + 458,610,008 or 459,610,008 or 4.59610008 x 10 ⁸
How big are the actual stairs in the office building? To make a scale model you first need to know the dimensions of the original model.
Answer:
Step-by-step explanation:
- Total distance = 10 miles
- Total time = 2 hours
- Distance walked = x
- Speed walked = 2 mph
- Distance cycled = 10 - x
- Speed cycled = 15 mph
<u>Using the given data we can have the equation below to the time:</u>
- x/2 + (10 - x)/15 = 2
- 30x/2 + 30(10 - x)/15 = 30(2)
- 15x + 20 - 2x = 60
- 13x = 60 - 20
- 13x = 40
- x = 40/13
- x = 3.08 miles <em>rounded to 2 decimal places</em>
