Question

3 a. john rides his motorcycle 384 km in 4 hours. what is his average speed in kilometers per hour? 3 b. an airplane flies with a constant speed of 600 miles per hour. how long will it take to travel a distance of 1500 miles?

Explanation:

Step1: Recall speed formula

$\text{Speed} = \frac{\text{Distance}}{\text{Time}}$

Step2: Solve 3a: Calculate speed

$\text{Speed} = \frac{384}{4} = 96$ km/h

Step3: Rearrange formula for time

$\text{Time} = \frac{\text{Distance}}{\text{Speed}}$

Step4: Solve 3b: Calculate time

$\text{Time} = \frac{1500}{600} = 2.5$ hours

Answer:

3 a. 96 kilometers per hour
3 b. 2.5 hours
