Note the difference !
- it's not the "shorter trip"
- it's "if she travels from A to D directly, how much shorter will it be ?" that is to say 35 minus AD
Please see the attachment. You'll have to find distance AD. Think "Pythagoras".
The figure below shows the route Diane has to take. Diane travels 16 miles from A to B, 15 miles from B to C, and 4 miles from C to D. If she was able to travel from A to D directly, how much shorter, in miles, would the trip be?
I got the total original to be 35 miles. How do I find the 'shorter' trip? Thanks in advance
