Question

Mr Murray’s distance away (in meters) from his classroom after t seconds can be modeled by the following equation: M(t) = 3.5t + 2. After 3 seconds, how far is Mr Murray away from his classroom?

Answer 1

Using Mr. Murray's distance equation M(t) = 3.5t + 2, after 3 seconds (t=3), Mr. Murray is 12.5 meters away from his classroom.

Step-by-step explanation:

To determine how far Mr. Murray is from his classroom after 3 seconds, we use the equation M(t) = 3.5t + 2, where M(t) represents the distance in meters and t is the time in seconds. To find the distance after 3 seconds, we substitute t with 3:

M(3) = 3.5(3) + 2

M(3) = 10.5 + 2

M(3) = 12.5 meters

Therefore, after 3 seconds, Mr. Murray is 12.5 meters away from his classroom.

Answer 2

Substitute the given value of three into the equation so that it becomes

M= 3.5*3+2

M= 12.5
