Question

The speed limit on many highways is 70 miles per hour. When Carrie and her mom travel from Tallahassee to Jacksonville, her mom drives with an average speed of 70 miles per hour on the highway.

In one hour, how many kilometers do Carrie and her mom travel? Round your answer to the nearest whole number

Answer 1

does anyone know how to get that answer

Answer 2

Answer 3

i need the answer to the question not the that

Answer 4

you need to know that speed = distance / time
you now get speed = 70 miles per hour and time = 1 hour
Put the numbers into the formula
70 = distance / 1
So can you work out the answer?

Answer 5

Step one: Calculate the distance she travels in miles. Then convert the distance in miles to distance in km. Find the conversion for miles to km. Having spent 3 years in germany, I know that the km is less than a mile, so your answer in km will be larger than the number of miles.

Algebraic Steps / Dimensional Analysis
1 mi/hr * 5280 ft/hr
1 mi/hr
*
1 m/hr
3.2808 ft/hr *
1 km/hr
1000 m/hr = 1.609344 km/hr

Answer 7

so 113 km

Answer 8

\[1 mi/hr * 5280 ft/hr 1 mi/hr * 1 m/hr 3.2808 ft/hr * 1 km/hr 1000 m/hr = 1.609344 km/hr \]

Answer 9

Or do it that way, convert speed to km/hr and then in hour you will have the distance in km!
