And remember, the bigger number always goes on top! :P
Hope this helps!
Answer:
8/5
Step-by-step explanation:
60 miles per hour
distance=rate times time
first part
rate=60mph
time=3h
distance=60mph times 3h=180 miles
part 2
time=2 hours
rate=70mph
distance=70mph times 2h=140miles
total is 180mi+140mi=320miles
178-x=?
This expression is the answer
