# Compute the total change in distance and change in time
total_distance = ____[-1] - ____[0]
total_time = ____[-1] - ____[0]

# Estimate the slope of the data from the ratio of the changes
average_speed = total_distance / total_time

# Predict the distance traveled for a time not measured
elapse_time = 2.5
distance_traveled = average_speed * elapse_time
print("The distance traveled is {}".format(distance_traveled))
