Question

If Sally walked 1⁄2 kilometer in 1⁄4 hour, how fast, in kilometers per hour, was she walking?

Answer 1

2km/hr is the answer to the question

Answer 2

Sally walks at a speed of 2 kilometers per hour.

Explanation:

Given data

• Walked distance (d): 1/2 kilometer

• Elapsed time (t): 1/4 hour

We can find the speed (v) of Sally using the following expression

v = d/t = (1/2 km) / (1/4 h) = 2 km/h

Sally walks at a speed of 2 kilometers per hour.
