A car is traveling at a rate of
40 miles per hour. What is the car's rate in kilometers per hour? How many kilometers will the car travel in 2 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.
Rate = km over h
Distance traveled in 2 hours = km

is it @FaZe_Rainn
OpenStudy (anonymous):
if its is than the car would travel 128.748 kilometers in 2 hours @FaZe_Rainn
OpenStudy (anonymous):
40mphx1.6 = 64km/h
distance = 128 km
OpenStudy (johnweldon1993):
The above is correct
Rate = \(\large \frac{40miles}{1hour}(\frac{1.6km}{1mile}) = \frac{64km}{hour}\)
Now we know that they travel 2 hours...so if it is 64km per hour...times 2 would make it 128 km

thank you guys so much @johnweldon1993 :)
