Homework Statement
Hi
I read a question recently on the British Mensa website and I thought the answer was 112.5mph. The answer given was 108mph. What is the calculation for this scenario?
"Lap 1 is completed at 135mph, lap 2 is completed at 90mph, what’s the average speed?"
Homework Equations
summation and division of two numbers
The Attempt at a Solution
135 plus 90 equals 225. 225 divided by 2 eqals 112.5
Thanks.
