Answer:
d= 12.50 miles
Step-by-step explanation:
Kinematic equation of uniform motion (constant speed) :
v= d/t Formula (1)
v: velocity in miles per hour (mph)
d: distance in miles
t: time in hours
Data
v= 50 mph
t= 0.25 hours
Problem development
We replace data in formula (1)
50 mph=d/0.25 hour
d= 12.5 miles
d= 12.50 miles
Answer: 0.4 meters per hour.
Step-by-step explanation:
The rate of change of distance with respect to time is known as speed.
Formula :
Given : It's raining outside, and after 1 hour of rain, the water level in Jake's pond is 2 meters. After 3 hours, the water level is 2.8 meters.
i.e. Change in position= 2.8-2=0.8 meters
Change in time = 3-1=2 hours
i.e.
Hence, the rate of change =0.4 meters per hour.
