Hey! Im counting on you guys!

Ken drove 174 miles in 3 hours. The equation y = 57x represents the distance in miles, y, Brenda drove in x hours. Determine who had the faster driving speed and by how much.

Please form your answers like so:
Of the two drivers, (...) had the faster driving speed by (...) mile(s) per hour.

Answer 1

To find Ken's speed divide total distance by total time:

174 miles / 3 hours = 58 miles per hour.

In the equation for Brenda, the 57 is the miles per hour because you would multiply that by x ( hours) to get total miles (y).

Ken had the faster driving speed.
