Question

It took Ciera 24 minutes to drive 18 miles. It took chains of one hour to drive 46 miles. Who is driving at a faster rate?

Answer 1

After calculating their average speeds, Ciera's at 45 mph and James's at 46 mph, we can conclude that James is driving at a faster rate than Ciera.

Step-by-step explanation:

To determine who is driving at a faster rate, we need to calculate the average speed for both Ciera and the other driver. Average speed is defined as the total distance traveled divided by the total time taken to travel that distance.

For Ciera, her rate can be found using the formula:

1. Convert minutes to hours by dividing by 60: 24 minutes ÷ 60 minutes per hour = 0.4 hours.
2. Calculate her average speed: 18 miles ÷ 0.4 hours = 45 miles per hour.

For the other driver, assumed to be 'James' given the context 'chains of one hour', his rate is:

1. Since one hour is the time interval, no conversion is needed.
2. Calculate his average speed: 46 miles ÷ 1 hour = 46 miles per hour.

Comparing their speeds, we can conclude that James is driving at a faster rate than Ciera because 46 mph is greater than 45 mph.

Answer 2

Ciera is driving at a faster rate.

Step-by-step explanation:

You calculate speed, by dividing distance by time.

So 18 divided by 24 is 0.75. That is Ciera's speed.

And then to calculate the other person/thing's speed you have to divide 46 by 60 minutes (equal to one hour). The speed calculates to 0.7666666667

Therefore, Ciera is driving faster.
