Answer:
Time taken by Anna = x = 5.6 hours
Explanation:
Strategize. Let x = Anna's time.
We know that, d = s*t
Where,
d is distance
s is speed
t is time
Distance covered by Allen = 7 times 40 = 7*40 = 280
Distance travelled by Anna = x times 50 = 50x
Set up. 7(40)=x(50)
280 = 50x
Solve for x
x =
x = 5.6 hours
Identify. Anna's time is the unknown.
Solve. x = 5.6
Check. 7(40)=5.6(50)
280 = 280
You're right!
That's the final answer.
I hope it will help you.
