Speed and Distances
The formula for calculating distance is expressed as:
- Distance = speed * time
Given the following
Distance = 10 miles
a) If the speed is 2 miles per hour
Time = Distance/Speed
Time = 10/2
Time = 5 hours
B) If the speed is 2.5 miles per hour
Time = Distance/Speed
Time = 10/2.5
Time = 4 hours
C) If the speed is m miles per hour
Time = Distance/Speed
Time = 10/m
Time = 10/m hours
D) If the speed is 2 miles per hour more than m miles per hour, hence;
speed = m + 2
Time = Distance/Speed
Time = 10/(m+2) hours
E) If three times slower than m miles per hour, hence;
Speed = m - 3
time = 10/(m-3) hours
