The distance in meters should be divided by the time in seconds to get the value of the distance in meters travelled in one second.
In the problem, the first equation should be represented like this base on the variable given in the problem:
20p + 9t = 44.4
with that equation, the second equation would is given by this formula, in response with the additional number of paperback and textbook
21p + 14t = 51
to get the system equation in getting the mass of each variable, you should subtract the two equation to simplified the formula.
20p + 9t = 44.4
- 21p + 14t = 51
-------------------------
p + 5t = 6.6 // this is the system equation that could be use in getting the mass of each object
Answer: Aluminum ramps last much longer than wooden ramps - made from durable non-corrosive aluminum - provide proper traction and load distribution - ADA compliant in most states - maintain their value for resale - less hastle, everything you need in one box - assembles in hours, not weeks - building permits for residential use of pre-engineered ramps are typically not required.
