A commuter train travels 45 miles in 28 minutes. what is its speed in miles per hour?

Step-by-step explanation:

-First, you have to find how many miles per minute the train goes.

You do this by dividing 45 by 28.

you get 45/28 miles per minute

-Then, you multiply 45/28 miles per minute by 60.

45 times 60 is 2700.

2700 divided by 28 is 675/7 which is:

Mixed number form: 96 and 3/7 miles per hour

rounded to the tenth: 96.4 miles per hour

rounded to the hundredth: 96.43 miles per hour

rounded to the thousandths: 96.429 miles per hour

96.43 mph to the nearest hundredth.

Step-by-step explanation:

Speed in miles per minute = 45/28

To convert to mph we multiply by 60.

= (45*60)/28

= 96.429

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
