class starts at 8:30. it takes max 25 minutes to bicycle to school. at what time should he get to school if he wants to go 15 minutes early

Answers

Since class starts at 8:30, you would subtract 15 from 8:30 (Because he wants to be 15 minutes early)

It takes him 25 minutes to bike to school, and 8:15 -:25 is 7:50.

You can come to this conclusion by adding the two times, and subtracting them from 8:30 as well!

Answer:

He'd have to leave his house at 7:50

Step-by-step explanation:

If class starts at 8:30 and it would take him 25 minutes to get there, you could start out by subtracting 25 from 30 which would mean that he would usually have to leave at 8:05, and then subtract 15 from that to get 7:50, or you could add 25 and 15 together and subtract that from 8:30 to get 7:50.

On her way to visit her parents, Jennifer drives 265 miles in 5 hours. What is her average rate of speed in miles per hour?

Answers

Her average speed in miles per hour would be 53 mph.  You can get this by dividing the miles driven and the time.  This means Jennifer drove 53 mph to get to her parent's house. Hope this helps!
Average speed = Total distance / Time

                           =  265 miles / 5 hours

                           = 53 miles / hour.
