Question

1.) how much distance did the object travel during the entire trip? 2.) how long did the trip take? 3.) what is the average speed for the entire trip? graph a: distance (km) 0 1 2 3 4 5 0 5 10 15 20 25 30 35 40 45 time taken (minutes) graph b:

Explanation:

Step1: Determine distance

From the graph, the starting - point distance is 0 km and the ending - point distance is 5 km. So the total distance $d = 5$ km.

Step2: Determine time

The starting time is 0 minutes and the ending time is 45 minutes. So the total time $t=45$ minutes. Since speed formula is $v=\frac{d}{t}$, and we need to convert time to hours for speed in km/h. $t = 45\div60 = 0.75$ h.

Step3: Calculate average speed

Using the formula $v=\frac{d}{t}$, substituting $d = 5$ km and $t = 0.75$ h, we get $v=\frac{5}{0.75}=\frac{5}{\frac{3}{4}}=\frac{20}{3}\approx6.67$ km/h.

Answer:

1. The object traveled 5 km.
2. The trip took 45 minutes.
3. The average speed for the entire trip is $\frac{20}{3}\approx6.67$ km/h.
