Question

fast it is urgent answer by numbers it is extremely urgent​

Answer 1

Answer:

1) 72 km/h = 72× 5/18 m/s

= 20 m/s

2) 60 m/s = 60× 18/5

= 216 m/s

3) 10 km/h = 10 ×5/18 m/s

= 50/18 m/s

time= distance/ speed.

= 750 × 18/50 s

= 270 s = 4 min 30 second

4) distance= 500 m

time= 100 sec

speed= 500/100 m/s

= 5 m/s = 5× 18/5 km/h

= 18 Km/H

5) speed= 20 km/h= 20×5/18 m/s

= 100/18 m/s

time= 50 min = 300 sec

distance= 100×300/18 m

= 1000/6 m = 10/6 km.

hope this answer is clear to you
