A train travels at a constant rate of 145 miles per hour. a. What is the equation for this scenario?
b. A second train is traveling 300 miles in 2 hours. Which train is traveling faster? How do you
know?

a. r = d/t, 145(rate) = 145(distance)/1(time)

b. The second train is travelling faster

The first train has a rate of 145 mph the second has a rate of 150 mph since r = 300 miles/2 hours = 150

Therefore the second train has a rate of 150 mph while the first train has rate of 145 mph

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

they will manufacture 8496 cars
