Hello!

You divide the total time by the time unit for the slope

54 / 3 = 18

Multiply this by how height the cart goes

4 * 18 = 72

The answer is 72

Hope this helps!

Answer:

It takes 4.75 hours to travel 247 miles.

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

A car travels at an average speed of 52 miles per hour.

This means that in 1 hour, the car travels 52 miles. How many hours for it to travel 247 miles?

1 h - 52 m

x h - 247 m

Applying cross multiplication

$52x = 247$

$x = \frac{247}{52}$

$x = 4.75$

It takes 4.75 hours to travel 247 miles.
