Final answer:
Justine takes approximately 1207 steps to walk 0.70 km to her math class with a step length of 58 cm, so the closest answer is 1200 steps (Option C).
Step-by-step explanation:
The question asks us to calculate the number of steps Justine takes while walking 0.70 km to her math class, with an average step length of 58 cm.
To find the total number of steps, we first need to convert the distance from kilometers to centimeters because Justine's step length is given in centimeters:
0.70 km = 0.70 * 1000 * 100 = 70,000 cm
Now, we divide the total distance by the length of one step:
70,000 cm / 58 cm/step ≈ 1206.9 steps
Since we can't have a fraction of a step, we'll round this to the nearest whole number, which is 1207 steps. Among the options provided, the closest is:
C) 1200
