Answer:
The speed and time are directly proportional in that the higher the speed the lesser the time and vice versa.
The constant is the total distance which is 180 km
Step-by-step explanation:
Step one:
given data
The distance between the two cities is 180km
1.The distance was covered by a car at the rate of 50km/h
The time taken will be
velocity= distance/time
time= distance/velocity
time= 180/50
time= 3.6 hours
2.The distance was covered by a bus 45km/h
The time taken will be
velocity= distance/time
time= distance/velocity
time= 180/45
time= 4 hours
3.The distance was covered by a bicycle at 25km/h
The time taken will be
velocity= distance/time
time= distance/velocity
time= 180/25
time= 7.2 hours
Answer:
no.400pts is equal to 50 gallons.1pt equals 0.125 gallons 400 pints x0.125 gallons equals 50 gallons,so that statement is false
Step-by-step explanation:
1/2=5/10
1/5=2/10
1/2+1/5
=5/10+2/10
=7/10
So your answer is 7/10
3/4(-10+2/5)
first do parenthesis
factor out -1 inside the parenthesis
3/4 * (-1*(10-2/5))
borrow from the 10
3/4 * (-1*( 9 5/5-2/5))
3/4 * -1(9 3/5)
change the mixed number to an improper fraction
3/4 * -1 ((5*9+3)/5)
3/4 * -1(48/5)
3/4 * (-48/5)
-144/20
divide by 4
-36/5
-7 r 1
-7 1/5
Answer:500
