A garden snail moves at 0.03 mph. What is this speed in inches per second? Can u show the steps? Thanks

Answer 1

1)  150 x 11.377=1706.55

1706.55-1250=456.55 pesos

456.55 / 11.377= 40.129 or 40 dollars

2) 1 Inch =  0.000015782828283 Miles

so 0.03 / 60 [the minutes in a hour] = 0.0005 miles per minute

so 0.0005 / 60 [the seconds in a minute] = 8.3333333333333333333333333333333 exponent of -6 miles per second

convert

so 8.3333333333333333333333333333333 exponent of -6  X 0.000015782828283 = 0.000000000131523569025 inches per second

answer: 0.000000000131523569025 inches per second

XD

number two might be wrong

Answer 2

so she gets 150*11.377  = 1706.55 pesos

spends 1250 , so she has 1706.55 - 1250 left or 456.55

456.55 / 11.377 = 40.13 left, so $40.

.03 miles / hour * 5280feet / mile * 12 inches / feet * 1 hour / 60 min * 1 min/ 60 sec ==== 1900.8/3600 = .528inches/second

Answer 3

This is why you should pay attention in class instead of talking to your Friends. Call the nerd guy in you class the guy with no friends and ask Him to come over and help. I sure he will drop his mouse or controler and come over right away.
