Maria left the starting line at 8:30 a.m. and drove at an average rate of 40 mph. What time did she arrive at check point 1?

Somehow one needs distance.

distance= rate(time)

(d=rt)

You multiply the rate and the time and your answer is the distance.

Ex:
Rate= 5 per hour
Time: 2 hours
Whatever that is it equals the distance.

Help! It makes no sense!!!

To find out what time Maria arrived at checkpoint 1, we need to know the distance between the starting line and checkpoint 1. Without that information, I can't provide the exact time. However, I can explain how to calculate the arrival time based on the given average rate of 40 mph.

First, calculate the travel time by dividing the distance to checkpoint 1 by the average rate of 40 mph. If the distance is given in miles, simply divide the distance by the rate. Let's say the distance is d miles, then the travel time t (in hours) can be calculated as:

t = d / 40

Once you have the travel time, add it to the starting time of 8:30 a.m. to get the arrival time at checkpoint 1. For example, if the travel time is 2 hours, the arrival time would be:

8:30 a.m. + 2 hours = 10:30 a.m.

To obtain a specific answer, please provide the distance from the starting line to checkpoint 1.
