Suppose you are a detective assigned to a robbery case. in this case, the robbery occurred at 2: 30 pm. you have a witness who saw suspect at a gas station 12 miles from the robbery site at 2: 48 pm. the suspect claims innocence, arguing that it would have been impossible to get to the gas station in that amount of time. do you agree? support your answer.

Step-by-step explanation:

Time of robbery = 2 : 30 PM

Witness saw the suspect at the time = 2 : 48 PM

Difference in timings = 2 : 48 - 2 : 30 = 18 minutes

Distance of the robbery site and gas station = 12 miles

Speed by which suspect can drive to reach the gas station

=

= miles per minute

= miles per hour

= 40 miles per hour

Since 40 miles per hour is a nominal speed by which the suspect can easily reach the gas station.

Therefore, I don't agree with the suspect's statement that it is impossible to get to the gas station in that amount of time.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
