John took 45 minutes to bicycle to his grandmother's house, a total of four kilometers. what was his speed in km/hr?
1 answer:
We need to convert 45 min to hours.
There are 60 min in an hour.
45/60 = 0.75
45 minutes = 0.75 hour
(4 km)/(0.75 h) = 5.3333 km/h = 5 1/3 km/h

First, Jane must know the volume of the box.
Volume = l * w * h
Volume = 1 * 0.5 * 0.5
Volume = 0.25 yard^3
1 yard^3 = $25
So,
1 : 25 = 0.25 : x
x = 25 * 0.25
x = $6.25
So she need to spend $6.25
