The object is moving at the speed of 50 ms-1 .
6.9 m per second
7.84 minutes (7 minutes 50 seconds) to cover 4km at 8.5m/sec
7 m/s. (meters per second) or 25.2 km/h
The average speed = 1/2 (initial speed + final speed) = 1/2 (15 + 25) = 1/2 (40) = 20 meters per second.The distance traveled = (average speed) x (time) = (20 x 7) = 140 meters.
The object is moving at the speed of 50 ms-1 .
To find the speed, first convert 7 minutes and 35 seconds to seconds only (455 seconds total). Then, divide the distance (2000 meters) by the time (455 seconds) to get the speed: 2000 meters / 455 seconds = 4.40 meters per second.
speed = 525/75 = 7 meters per second distance = speed × time distance = 7 × 60 distance = 420 meters
50 x 7 = 350m

giraffe speed = 525 m / 75 s = 7 m/s Elephant speed = 260 m / 65 s = 4 m/s → The giraffe is the faster animal.
