Jack drove to work in the morning at an average speed of 45 miles per hour. He returned home in the evening along the same route
Dmitry [639]

Answer:

Step-by-step explanation:

Let's say that the time it took him to get to work in the morning is  t hours. Then the time it took him to get home in the afternoon must be 1 - t hours. We know that for any trip, distance equals rate times time or d = rt . That means that the distance he drove to work is given by , but we also know that the distance he drove to get home must be the same distance, because he took the same route (and, presumably, no one picked up him house and moved it while he was at work) so for the trip home we can say  d = 30 × (1 - t) and since the distances are equal, we can say: 

45t = 30 × (1 - t)

45t = 30 - 30t

45t + 30t = 30

75t = 30

t = 30/75

t = 2 /5 hour to drive to work at 45mph

Since ,  d = rt

d = 45 ×(2/5) = 18miles

olga2289 [7]

Answer:

1200d rops of red coloring

800 drops of blue coloring

Step-by-step explanation:

The first thing is to make your pints and gallons the same unit. Todo  this multiply 50 (the total amount of gallons) by 8 (the number of pints in a gallon)

50*8=400

next, multiply the drops of coloring out.

To do this multiply 400 by 3 drops for red

400*3=1200

Then Multiply 400 by 2 for blue

400*2=800
