Question

Solving a word problem involving rates and time conversion
A car travels at an average speed of 52 miles per hour. How long does it take to travel 247 miles?

Answer 1

Answer:

It takes 4.75 hours(4 hours and 45 minutes) to travel 247 miles.

Step-by-step explanation:

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

52 miles in one hour. How many hours for 247 miles?

1 hour - 52 miles

x hours - 247 miles

Applying cross multiplication:

$52x = 247$

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

$x = 4.75$

It takes 4.75 hours = 4 hours and 3/4*60 = 45 minutes to travel 247 miles.
