A mars rover traveled from point a to point b at a speed of 4 cm/sec. Worsening conditions during the return trip caused the rov
miskamm [114]

Using a system of linear equations, the distance between points A and B is 6000 cm

  • Initial speed = 4cm/sec

Time taken = Distance / speed

Let ; distance = d

<u>To</u><u> </u><u>time</u><u> </u><u>:</u><u> </u>

  • <u>t</u> = d / 4
  • <em>4t = d ______(1)</em>

<u>Fro</u><u> </u><u>time</u><u> </u><u>:</u><u> </u>

(t + 15 × 60) = d / 2.5

2.5(t + 900) = d

<em>2.5t + </em><em>2250</em><em> = d ______(2)</em>

Equate (1) and (2)

4t = 2.5t + 2250

4t - 2.5t = 2250

1.5t = 2250

t = 1500 seconds

From (1) :

d = 4t

d = 4(1500)

d = 6000 cm

Therefore, the distance from point A to B is 6000 cm

If 7m = 35, then 7m + 4 = 35 + 4<br> NAME THE PROPERTY
Reptile [31]

The property that is applied in 7m+4=35+4 is addition property of equality

Given :

If \; 7m=35, then \; 7m+4=35+4

From the above equation we can see that 4 is added at the both sides of the equation .

we can add same number at the both sides of the equation to balance the equation . That is called as addition property of equality
