The mathematical expression of the distance between the ground and coin is (y = 160 - 30x) and this can be determined by forming the linear equation.
Given :
Melissa threw a coin from a bridge 160 feet high with an initial speed of 30 feet per second.
The following steps can be used in order to determine the expressions that can be used to determine when the coin will hit the ground:
Step 1 - Let 'x' be the distance covered by the coin.
Step 2 - Now, let the distance between the ground and the coin be 'y'.
Step 3 - So, the mathematical expression of the distance between the ground and coin is given below:
y = 160 - 30x
