At the start of a trip, the odometer on a car read 21,395. at the end of the trip, 13.5 hours later, the odometer read 22,125. assume the scale on the odometer is in miles. what is the average speed the car traveled during this trip?

54.81 mph

Explanation:

Initial reading on the odometer = 21395 miles

Final reading on the odometer = 22125 miles

Total time the car travelled =  13.5 hours

Distance covered by the car

22125-21395 = 740 miles

As acceleration is not given assume it as constant.

Speed = Distance / time

∴ Average speed the car traveled during this trip is 54.81 mph

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
