Trey runs 3 miles in 25 minutes. At the same rate, how many miles would he run in 20 minutes?

aalyn [17]

Answer:

Step-by-step explanation:

Set up a proportion.

3/25 = x / 20 Notice that both times are in the denominators. Be sure you always set up a proportion that way. Like units in the denominator. Like units in the numerator.

Cross multiply

3 * 20 = 25 * x Combine

60 = 25x Divide by 25

60/25 = x

x = 2.4 miles in 20 minutes.

translate this sentence into an inequality. A cheetah can reach a speed of 70 mph. however, this speed can be maintained for no

Gre4nikov [31]

<h2>Hello!</h2>

The answer is:

B. $d\leq 1,640ft$

From the statement we know that the cheetah can reach a speed of 70 mph, but it can be maintained for no more than 1,640 feet.

The expression "no more than" means that at least it can be reached but never exceeded, it involves that the distance can be less or equal than 1,640 feet but never more than that.

So, the correct option is:

B. $d\leq 1,640ft$
