The number of Euros received against 600 dollars = 450
Then
For 1 dollar, the number of euros = (450/600) euros
= (45/60) euros
= ( 3/4) euros
= 0.75 euros
So the unit rate that describes the exchange rate is 0.75 euros per dollar. So the correct option among all the options given in the question is option "A".
I hope the procedure for
getting to the correct result is clear enough for you to understand. In future
you can use this procedure for solving similar problems.
solve for "l" to find its length
Oliver traveled 124.25 miles in 3.5 hours at a constant speed
Rate = 124.25 / 3.5 = 35.5 miles per hour (MPH)
Answer:
The constant of proportionality is 35.5 miles per hour (MPH)
Answer:
Four is the final answer (4)
Step-by-step explanation: Have a brilliant day of learning!
I hope this helps you
distance=speed×time
first cars time t
second cars time t+3
same distance
distance=55.t
distance=40. (t+3)
55t=40 (t+3)
55t-40t=120
15t=120
t=8
t+3=11
