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: graph of distance - time with distance in km on x - axis and time taken in minutes on y - axis graph b:

Explanation:

Step1: Determine the total distance

The object starts at 0 km and ends at 5 km, so the total distance $d = 5$ km.

Step2: Determine the total time

The object starts at 0 minutes and ends at 45 minutes, so the total time $t=45$ minutes. Since speed is usually in km/h, convert 45 minutes to hours. $45$ minutes $=\frac{45}{60}= 0.75$ h.

Step3: Calculate the average speed

The formula for average speed $v=\frac{d}{t}$. Substitute $d = 5$ km and $t = 0.75$ h into the formula. $v=\frac{5}{0.75}=\frac{5}{\frac{3}{4}}=\frac{20}{3}\approx6.67$ 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.
