7 hours APPOX
Step-by-step explanation:
Step one:
given data
Rachel drives an average of 50 miles per hour on a trip
speed= 50 mph
distance= 345 miles
Step two:
speed=distance/time
time= distance/speed
time= 345/50
time= 6.9 hours
time= 7 hours APPOX
<span>The object's speed is 8/5 miles per hour or 1.6 mph.</span>
I think in this situation the best method would be a guess and check. You know that there are 8 dimes more than there are nickels. So just keep increasing each number by one until you reach $1.40. If there were 9 dimes and 1 nickels it would add up to $0.95. If there were 10 dimes and 2 nickels, it would add up to $1.10. If there were 11 dimes and 3 nickels, it would add up to $1.25. If there were 12 dimes and 4 nickels, it would add up to $1.40. So your answer is 12 dimes and 4 nickels.
I hope this helped!
Answer:
To divide by a decimal, multiply the divisor by a power of ten to make the divisor a whole number. Then multiply the dividend by the same power of ten. You can think of this as moving the decimal point in the dividend the same number of places to the right as you move the decimal point in the divisor
