Answer:
a) The height of the image = 11.2 millimeters
b) The distance between the camera and her friend = 2.24 meters
Step-by-step explanation:
<u>Part A: find the height of the image:</u>
distance from the lens to the film = 24 millimeters
distance from the lens to the her friend = 3 meters = 3000 millimeters
height of her friend = 140 centimeters = 1400 mm
the height of the image = x
Using the similarity :

Answer:
v = 23.370 mph
Step-by-step explanation:
It is given that,
The world record for the 100 meter dash is finished in 9.572 seconds in Berlin. We need to find the Bolt’s average race speed in miles per hour.
We know that,
1 mile = 1.609 km
or
1 mile = 1609.34 m
⇒ 100 m = 0.0621 miles
1 hour = 3600 seconds
⇒ 1 second = (1/3600) hour
Average speed = distance/time
So,
or
v = 23.370 mph
Hence, Bolt’s average race speed is 23.370 mph.
