Answer:
A can paint in 3days and B in 6 days
Step-by-step explanation:
From the question we were told
Person A can paint the neighbors house 2 times as fast as Person B
Let A only paint the neighbors house in X days
Let B only paint the neighbors house in 2X days
If we express the given information from the question in terms of fraction we have,
1/X + 1/2X = 1/2
3/2X = 1/2
if we cross multiply we have
6= 2X
X= 6/2
X= 3
Then A can paint the house in 3 days and B in 2(3)= 6days.
Car 1. (40 kph):
40 kph = 40,000 km per hour
Car 2. (15 mps)
15 mps x 60 (to get one minute) = 900 mpm
900 meter per minute
900 x 60 = 54,000 km
Therefore, car 2 is faster since it drives at 54km per hour and car 1 only travels at 40km per hour.
Also, you decide which car you want to choose.
Hope this helps! Have a great day.
