The Guzman family=45mph
The Hashimoto family=60mph
The next palindromic number is 16061, so he traveled 110 miles. 110 miles/2 hours = 55 mph.
I believe the answer would be 46 students
> 46 Students in Tom's school are Left-Handed
you can subtract from point 1 to point 2
(9,-2) - (8,3)
9-8= 1
-2-3= -5
therefore horizontal leg is 1
vertical leg is -5
you can also sketch and count the units :)
