If the faster car is travelling 20 mph faster then slower car then the speed of slower car is 55mph and faster car is 75 mph.
Given that the faster car is travelling 20 mph faster than slower car and when slower car travels 165 miles the faster car travels 225 miles.
We are required to find the speed of slower car and faster car.
let the speed of slower car be x mph.
In this way the speed of faster car be (x+20) mph.
Speed=Distance/ time
We have to first take slower car.
x=165/Time
Time=165/x-----------1
Now by taking faster car.
x+20=225/time
Time=225/(x+20)-------2
From equation 1 an equation 2.
165/x=225/(x+20)
225x=165x+3300
225x-165x=3300
60x=3300
x=55 mph
Faster car=55+20
=75 mph.
Hence if the faster car is travelling 20 mph faster then slower car then the speed of slower car is 55mph and faster car is 75 mph.

Answer: No
Step-by-step explanation: she has $50
To find % you would multiply the original number by the percentage.
It would be 50*0.06 (percentages are simplified by dividing it by 100)
50*0.06=3
48.20+3=51.20
So the answer would be No Jessica does not have enough to buy the jacket.
Answer:
43 1/3 minutes to iron 10 shirts
Step-by-step explanation:
Number of shirts : Time taken
3 shirts : 13 minutes
10 shirts : x minutes
3 / 13 = 10 / x
Cross product
3 * x = 13 * 10
3x = 130
Divide both sides by 3
3x / 3 = 130 / 3
x = 43 1/3 minutes
x = 43 minutes 20 seconds
It will take 43 minutes 20 seconds to iron 10 shirts
