Recall / Warm-Up

A cyclist travels at 10 km/hr for 2 hours. Which formula finds the distance covered?

Distance = Speed × Time = 10 × 2

Distance = Speed ÷ Time = 10 ÷ 2, since dividing is the operation used in the original speed formula.

Distance = Speed − Time = 10 − 2, since subtracting seems like a simpler way to combine the two given numbers.
