Question

examine the table here with the distances and times recorded for five different vehicles. calculate the average speed for each vehicle and select the options that are correct below. select all that apply.

a vehicle a had the slowest average speed.
b vehicle e had the highest average speed.
c vehicle b had a faster speed than vehicle d.
d vehicle c had a faster speed than vehicle d.
e vehicle d had an average speed of 35 kilometers per hour.

vehicle	distance (kilometers)	time (hour)
b	80	2.5
c	90	1.8
d	35	1.0
e	20	0.5

Explanation:

Step1: Calculate average speed for each vehicle

Average speed = $\frac{\text{Distance}}{\text{Time}}$.

• A: $\frac{40}{2.0}=20$ km/h
• B: $\frac{60}{2.5}=24$ km/h
• C: $\frac{60}{1.5}=40$ km/h
• D: $\frac{35}{1.0}=35$ km/h
• E: $\frac{20}{0.5}=40$ km/h

Step2: Evaluate each option

• A: Vehicle A's speed (20) is slowest. Correct.
• B: Vehicle B's speed (24) < D's (35). Incorrect.
• C: Vehicle C's speed (40) > D's (35). Correct.
• D: Highest speeds are C (40) and E (40), not only D. Incorrect.
• E: Vehicle D's speed is 35, not 30. Incorrect.

Answer:

A. Vehicle A had the slowest average speed, C. Vehicle C had a faster speed than vehicle D
