Question 1 (2 points) The total distance in centimeters a toy robot moves varies directly with the time in seconds. The toy robot moves a total distance of 264 centimeters in 11 seconds. a. What is the time in seconds the toy robot moves when the total distance is 408 centimeters? Seconds b. What is the distance in centimeters the toy robot moves after 3 seconds? Centimeters

a.    

b.    

Step-by-step explanation:

Given

Direct Variation

D = 264 cm when T = 11 s

Calculating (a)

First, the constant of variation (k) as to be calculated;

Since, there exist a direct proportion; then,

Make k the subject of formula

D = 264 cm when T = 11 s; So

So: Solving for (a)

Substitute 408 for D and 24 for k in

Divide both sides by 24

Hence, time to move a distance of 408cm is 17s

Calculating (b)

Substitute 3 for T and 24 for k in

Hence, distance covered in 3 seconds is 72cm

1/3 + 1/5 = 8/15.
