A helicopter ambulance flew from one hospital to another in a straight line. The pilot had to change speed several times due to the presence of other aircraft. The helicopter flew 20 kilometers in 8 minutes. What was the average speed of the helicopter during the trip? Group of answer choices 2.0 km/min 2.5 km/min 4.0 km/min 7.5 km/min

2.5 km/min.

Explanation:

Hello!

In this case, when an object moves a certain distance and the elapsed time is analyzed, we can compute the average velocity it had for that displacement, which can be quantified as shown below:

Whereas d stands for the distance, t for the time and v for the average speed. Thus, since the mentioned helicopter took 8 minutes to travel 20 km, we can compute the average speed as shown below:

Best regards!

it can be icreased by increasing pressure.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
