Answer:
198
Step-by-step explanation:
The ones digit must be 8. The tens digit must be 5 or greater. Since it only has one hundred, it could be any of ...
158, 168, 178, 188, 198
We will say that the eastbound cyclist is going x mph. This means that the westbound cyclist is going x+3 mph.
They are both cycling for 6 hours and end up 162 miles apart.
Distance=rate*time
6x+6(x+3)=162
6x+6x+18+162
12x=144
x=12
So, the eastbound cyclist is going 12 mph.
Remember the westbound cyclist is going 3 mph faster, so s/he is going 15 mph.
Hope this helps!!
