Question

As you get in the car to make a trip to the Bronx Zoo, you check the time. It was 10:30 a.m. It is approximately 140 miles away from your grandmother's house, which is where you are staying. You decide to take a day trip there, and you get there around 1:30 p.m. Figure out your grandmother's average speed.

A) 46.67 mph.
B) 60 mph.
C) 70 mph.
D) 80 mph.

Answer 1

The average speed is calculated by dividing the total distance by the total time.

Step-by-step explanation:

To calculate the average speed, we need to use the formula:

Average speed = total distance / total time

In this case, the total distance is 140 miles and the total time is 3 hours (from 10:30 am to 1:30 pm). So, the average speed is:

Average speed = 140 miles / 3 hours = 46.67 mph

Therefore, the correct answer is A) 46.67 mph.
