Question

If a dog runs 5 miles in 15 hours, what is its rate in miles per hour?

A) 5 mph
B) 10 mph
C) 1/3 mph
D) 1/15 mph

Answer 1

To find the rate in miles per hour at which a dog runs if it covers 5 miles in 15 hours, we use the formula 'Rate = Distance ÷ Time'. This gives us a rate of 1/3 mile per hour, which is answer C.

Step-by-step explanation:

The question asks to find the rate at which a dog runs in miles per hour if it runs 5 miles in 15 hours. To calculate the rate of speed, you divide the distance traveled by the time taken. The formula for the rate is:

Rate = Distance ÷ Time

Applying this formula:

Rate = 5 miles ÷ 15 hours = 1/3 mile per hour

The dog's rate of speed is therefore 1/3 mph, which corresponds to answer choice C.
