Question

What is your speed (in m/s) if you walk 1000m in 20 minutes? (Hint: how many seconds are in a minute)

A) 0.5 m/s
B) 1.0 m/s
C) 1.5 m/s
D) 2.0 m/s

Answer 1

To find the speed in m/s, convert the time in minutes to seconds and then divide the distance (1000m) by the time (1200s), yielding approximately 0.8333 m/s which is closest to option B) 1.0 m/s.

Step-by-step explanation:

To calculate speed in meters per second (m/s), we can use the formula: speed = distance ÷ time. The student walks 1000 meters in 20 minutes. First, we need to convert the 20 minutes into seconds because the speed must be in meters per second. There are 60 seconds in one minute, so 20 minutes is equal to 20 × 60 = 1200 seconds. Now we can calculate the speed: speed = 1000 meters ÷ 1200 seconds = 0.8333... m/s. However, since this wasn't one of the options provided, and rounding is necessary, the closest answer to 0.8333... m/s would be: B) 1.0 m/s.
