the track team is trying to reduce their time for a relay race. First they reduce their time by 2.1 minutes. then they are able
koban [17]

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 t_{1}. Then they are able to reduce that time by 10 minutes, take it as t_{2}. 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,

            X-t_{1}-t_{2}=3.96 \text { minutes }

            X=3.96+t_{1}+t_{2}

By substituting the values, we get

            X=3.96+2.1+10=16.06 \text { minutes }

Hence, their beginning time was 16.06 minutes.

A rectangular floor tile is shown.
ddd [48]

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
