The speed of the Shanghai Maglev train can be calculated by dividing the total distance traveled (2144 miles) by the total time (8 hours), yielding a result of 268 miles per hour.
To answer the question of how many miles the Shanghai Maglev train travels in an hour, you need to understand the concept of speed. Speed is defined as the distance traveled per unit of time. It is usually used in contexts where the direction doesn't matter, like this one.
The Shanghai Maglev train travels 2144 miles in 8 hours. We can find out how much it travels in an hour by dividing the total distance (2144 miles) by the total time (8 hours).
So this would be: 2144 miles ÷ 8 hours = 268 miles/hour.
Therefore, the Shanghai Maglev train travels 268 miles in an hour.

Complete the equation so that it has infinitely many solutions.
Answer:
2368.75 total cost
Step-by-step explanation:
3.75% divided by 100 = 0.0375.
Then 4500 X 0.0375= $168.75.
2,200 + 168.75 = 2,368.75.
= 2,368.75 total cost.
The unit rate of the bicyclist's speed is found by dividing the distance covered (1/5 mile) by the time spent (1/65 hour). The result is 13 miles per hour.
In this problem, you're asked to find a unit rate. A unit rate is a rate in which the second term is 1. So, to find a unit rate, you divide the first term with the second term.
In this case, the bicyclist's rate is 1/5 mile in 1/65 hour. If you divide 1/5 by 1/65, you find the rate of bicycle speed per 1 hour, which is the unit rate:
1/5 miles divided by 1/65 hours = (1/5) * (65/1) = 13 miles/hour
So, the bicyclist's unit rate is 13 miles per hour.
