Answer:
2 hours 30 minutes
Step-by-step explanation:
Given data
speed= 110mph
distance travelled= 275miles
Required
the time of travel
We know that
Speed= distance/time
time= distance/speed
time= 275/110
time=2.5 hours
Hence the time is 2 hours 30 minutes
Use the distributive property and multiply everything in the parentheses by 14.
Leaving you with.. (70 - 3.5 x 350) + 2 / 4 x 1.
Then reduce the parentheses.
Leaving you with.. ( -1155) + 2 / 4 x 1
Then divide 2 by four.
Leaving you with.. (-1155) + .5
Answer.. -1,154.5
