Their beginning time was 16.06 minutes.
<u>Step-by-step explanation:</u>
The track team is trying to reduce their time for a relay race.
First they reduce their time by 2.1 minutes, take it as
. Then they are able to reduce that time by 10 minutes, take it as
. Let ‘X’ be the time in minutes at the beginning.
Given that their final time is 3.96 minutes, then their beginning time can be calculated as below,


By substituting the values, we get

Hence, their beginning time was 16.06 minutes.

The maximum force in Newtons that can be safely applied to the tiles is; 735 N
<h3>How to calculate the force from pressure?</h3>
We are given the dimensions of the rectangular floor as;
Length = 1.6 m
Width = 2.3 m
Now, we are told that the tile is only able to sustain a maximum pressure
of 200 Newtons per square metre (N/m²). The formula for pressure here is; Pressure = Force/Area
Thus;
Force = Pressure * Area
Maximum force = 200 * (1.6 * 2.3)
Maximum force = 736 N
Since the Pressure was approximated to the nearest 5 N/m², then;
Maximum pressure will be approximated downwards to 735 N/m²

Nope. They are not equal.
