Final answer:
To calculate speed, you need to divide the distance the amoeba travels by the time it took, which is 24.5 seconds in this case. The actual distance in millimeters between the squares b3 to g7 needs to be provided to perform the calculation. Once you have the distance, divide it by the time, then round the result to the nearest hundredth to find the speed in millimeters per second.
Step-by-step explanation:
The student has asked how to calculate the speed of an amoeba that moves from square b3 to square g7 in 24.5 seconds. To calculate speed, we need to divide the total distance traveled by the time it took to travel that distance. However, the question does not provide the actual distance in millimeters between the two squares, so we'll need that measurement to proceed. If we had the distance in millimeters, we would then divide that by the time, 24.5 seconds, to find the amoeba's speed in millimeters per second. After calculating the speed, we would round the answer to the nearest hundredth as instructed.
For example, if the distance was 75.9 millimeters, we would calculate the speed as follows:
- Speed = Distance ÷ Time
- Speed = 75.9 mm ÷ 24.5 s
- Speed = 3.0984 mm/s which would be rounded to 3.10 mm/s
Since the question does not provide the actual distance, we are unable to complete the calculation. Therefore, to find the speed in millimeters per second, the student needs to measure the distance between the two squares on their grid or map.
