First we can find out how many miles he travels each hour.
# of miles he travels per hour = 174 miles / 3 hours
# of miles he travels per hour = 58 mph
He travels 7 hours so multiply the # of miles he travels per hour by 7.
58mph x 7h = 406 miles
Martin can travel 406 miles in 7 hours.
$40 minus the $2 for the water bottle = $38 minus the $20 he has remaining = $18 divided by the 4 water bottles he bought = 4.5 which is $4.50

Answer:
s=10
Step-by-step explanation:
Basically, the range rule-of-thumb is that the range is generally about four times the standard deviation.
<u>First, we find the range:</u>
Range=Maximum-Minimum
Range=100-60
Range=40
<u>Next, divide the range by 4 to get the standard deviation</u>
Range=4(Standard Deviation)
40=4(Standard Deviation)
10=Standard Deviation
Therefore, s=10, which is the standard deviation
