Question

Person moves from point X to point Y by covering a distance of 250 m in 25 seconds and comes back to point A in 15 seconds. Find 4 a) Distance covered by him​

Answer 1

400m

Because,

Distance travelled in 1 second = 250/25 =10

Distance travelled in 15 seconds = 10*15 = 150

Total distance travelled = 250+150 = 400 meters.

Hope it helps :) Mark as brainliest if u like my answer!!

Answer 2

Answer:

150m+250m=400m

Explanation:

$speed = \frac{distace}{time} = \frac{250}{25} \\ = 10mper \: second \\ \\ distance \: covered \: \: in \: 10 \: second \\ = 10 \times 15 = 150m$

distance from X to Y =250m

distance from Y to A =150m

total distance = 250+150=400m
