A boy rides his bike at a speed of 28 miles per hour. How

sergejj [24]

Answer:

About 4 hours.

Step-by-step explanation:

Let's set up a proportion and cross multiply.

$\frac{28 miles}{1 hour} = \frac{120 miles}{x}$

Cross multiply.

120 = 28x

Divide by 28 on both sides.

= 4.28571428571

Round this to the nearest whole number, which is just 4. The answer is about 4 hours.

Use two sets of coordinates to write an equation<br> to describe the relationship.

Irina-Kira [14]

Answer/Step-by-step explanation:

An equation that describes the relationship can be written as $y = mx$ .

Using the two sets of coordinates, (2, 140) and (4, 280), calculate the slope (m) as shown below:

$\frac{y_2 - y_1}{x_2 - x_1} = \frac{280 - 140}{4 - 2} = \frac{140}{2} = 70$

Substitute m = 70 into $y = mx$

The equation would be:

$y = 70x$

This equation can be interpreted as follows:

The heart's resting rate is 70 beats each minute.
