1. a car travels 363 miles in 2 hours and 45 minutes. Work out the average speed. 2. A car travels at 72 mph for 3 hours and 40 minutes.

How far has it travelled?

1. Average Speed is distance divided by time. So 363 divided by 165 is 2.2

2. For number 2 I am not sure if there is a missing piece to your question but the car has travelled 72 miles in 220 minutes

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
