Ilya and Anya each can run at a speed of 7.70 mph and walk at a speed of 3.30 mph . They set off together on a route of length 5.00 miles . Anya walks half of the distance and runs the other half, while Ilya walks half of the time and runs the other half.
Homework Answers
Anya's time, t = (2.5/7.7) + (2.5/3.30) = 1.08 hrs
Average speed, v = 5/1.08 = 4.62 mph
Ilya's average speed, v = (7.7 + 3.3)/2 = 5.5 mph
Time, t = 5/5.5 = 0.91 hrs

The distance a vehicle travels can be calculated as follows: distance = speed * time. For example, if a train travels 40 miles per hour for three hours, the distance traveled is 120 miles. Write a program using python that asks the user for the speed of a vehicle in mph and the number of hours it has traveled. It should then use a while loop to display the distance the vehicle has traveled for each hour of that time...

An ant is taking a two-dimensional random walk on a flat surface. We will distinguish steps that the ant takes with its feet from the random walk (RW) steps, of length δ, which are made up of lots of footsteps. In a RW step, the ant choose a direction randomly and walks distance δ in that direction. She then choose another direction randomly and walks distance δ in that direction. She repeats this for a total of n RW steps....
