Answer:
For the first 30 minutes, we will have a line with a given steepness, this will represent the 30 minutes riding at a fast pace.
Then he stops for 20 minutes, we will represent this with a constant line.
Then he again moves for another 30 minutes, but with a slower pace than in the first 30 minutes, then this line will be less steep than the first line.
A sketch of this situation can be seen below.
Answer:
6 hours
Step-by-step explanation:
180 divided by 30 = 6
The distance between the two cars is now 320 yards.
<h3 /><h3><u>
Distances</u></h3>
To determine what is the distance between the two cars now if they did not collide the following calculation must be performed:
- 500 - (500 - 405) - (500 - 415) = X
- 500 - 95 - 85 = X
- 500 - 180 = X
- 320 = X
Therefore, the distance between the two cars is now 320 yards.
