Question

Solving a word problem involving rates and time conversion

Answer 1

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.
