Question

how much distance is covered by a body in time 5 second if it's speed is 90 km/ h​

Answer 1

Answer:

Step-by-step explanation:

$speed=\frac{distance}{time} \\distance=speed*time\\ =90*5\\ =450$

Answer 2

Step-by-step explanation:

time = 5 seconds

speed = 90km/ h

1hour = 90km

60 × 60 = 90km

3600 seconds = 90km

1 second = (1÷3600) × 90

1÷40 km

5seconds = (1÷40) × 5

1÷8km

speed = 1÷8km

time = 5 seconds

distance= speed × time

(1÷8) ×5

5÷8.
