Question

Super Mario runs across the screen of your Chromebook at a speed of 8 cm per second. In the time that it takes Mr. Mel to tell you to stop playing Super Mario (which is about 3.5 seconds), how far did Mario move?

a) 28 cm
b) 25 cm
c) 30 cm
d) 20 cm

Answer 1

In 3.5 seconds, Super Mario moves at a speed of 8 cm per second. Mario moved 28 cm in that time.

Step-by-step explanation:

In 3.5 seconds, Super Mario moves at a speed of 8 cm per second. To find how far Mario moved, we can multiply the speed (8 cm/s) by the time (3.5 s):

Distance = Speed × Time = 8 cm/s × 3.5 s = 28 cm

Therefore, in the time it took Mr. Mel to tell you to stop playing Super Mario, Mario moved a distance of 28 cm. To calculate how far Super Mario moved across the screen of your Chromebook when running at a speed of 8 cm per second, you need to use the formula distance = speed × time. Given that the time Mr. Mel takes to tell the student to stop playing Super Mario is about 3.5 seconds, we multiply the speed by the time:

Distance = 8 cm/s × 3.5 s = 28 cm

Therefore, the answer is (a) 28 cm. Super Mario traveled a distance of 28 cm across the screen in that time frame.
