Question

Find the average speed for the given distance and time. Include the

units of measure in your answer.
16. An airplane travels 770 miles in 120 minutes.
17. A friend jogs 2 miles in hour.
18. A car travels 244 kilometers in 24 hours.

Answer 1

Explanation:

16 - Average Speed = 770 miles / 2 hours

Average Speed = 385 miles per hour

17 - Average Speed = 2 miles / 1 hour

Average Speed = 2 miles per hour

18 - Average Speed = 244 kilometers / 24 hours

To simplify the fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 4

Average Speed = (244 ÷ 4) kilometers / (24 ÷ 4) hours

Average Speed = 61 kilometers / 6 hours

Therefore, the average speed of the car is 61 kilometers per 6 hours.
