The speed is 57.5 m/s and the parachutist will fall 1150 m in 20 seconds.
Explanation:
We start out with the ratio 207 km/1 hr.
We know that 1 km = 1000 m; this means 207 km = 207*1000 = 207000 m. This gives us 207000 m/1 hr.
We know that 1 hr = 60 minutes, so we have 207000 m/60 min.
We also know that 1 min = 60 seconds, so 60 min = 60*60 = 3600 sec; this gives us 207000 m/3600 sec.
Dividing this, we get 57.5 m/s.
In 20 seconds, the parachutist will fall 57.5(20) = 1150 m.

Answer:
1150 meters
Step-by-step explanation:
Speed of parachute = 207 kilometers per hour
Speed of parachute in meter /second = (207 x 1000)/ (60 x 60)
= 57.5 meter /second
Parachute fall for 20 seconds with a speed of 57.5 meter /second, Thus the distance covered in 20 seconds
= 57.5 meter /second x 20 seconds
= 1150 meters.
