Question: If a car\'s speed is measured as 60 km/h with an error of ±2 km/h, what is the range of possible speeds?

Options:

Correct Answer: 58 to 62 km/h

Solution:

Range of possible speeds = Measured speed ± Error = 60 ± 2 gives 58 to 62 km/h.

If a car's speed is measured as 60 km/h with an error of ±2 km/h, what is the range of possible speeds?

If a car's speed is measured as 60 km/h with an error of ±2 km/h, what is the range of possible speeds?

Step 1: Identify the measured speed of the car, which is 60 km/h.
Step 2: Identify the error in the speed measurement, which is ±2 km/h.
Step 3: Calculate the lower limit of the speed by subtracting the error from the measured speed: 60 km/h - 2 km/h = 58 km/h.
Step 4: Calculate the upper limit of the speed by adding the error to the measured speed: 60 km/h + 2 km/h = 62 km/h.
Step 5: Combine the lower and upper limits to find the range of possible speeds: 58 km/h to 62 km/h.
