Question

Amanda traveled at a rate of 25 kilometers per hour, and Brenda traveled at a rate of 0.2 miles per minute (1 mile = 1.61 kilometers). Who traveled at a greater rate?

a) Amanda
b) Brenda
c) Equal rates
d) Insufficient information to determine

Answer 1

After converting Brenda's speed to the same units as Amanda's, we find that Amanda traveled at a greater rate of 25 kilometers per hour compared to Brenda's 19.32 kilometers per hour.

Step-by-step explanation:

To determine who traveled at a greater rate between Amanda and Brenda, we need to compare their speeds in the same units. Amanda's speed is given as 25 kilometers per hour. Let's convert Brenda's speed from 0.2 miles per minute to kilometers per hour.

First, we'll convert miles to kilometers:

0.2 miles × 1.61 kilometers/mile = 0.322 kilometers

Now, convert minutes to hours:

0.322 kilometers/minute × 60 minutes/hour = 19.32 kilometers/hour

Amanda traveled at a rate of 25 kilometers per hour, while Brenda traveled at a rate of 19.32 kilometers per hour. Therefore, Amanda traveled at a greater rate.
