Answer:
Average speed is 48 km per hour
Step-by-step explanation:
A student drove to the university from her home and noted that the odometer reading of her car increased by 16.0 km. The trip took 20.0 min. (a) What was her average speed? in km/hr
Distance traveled is 16 km and the time taken is 20 minutes
convert minutes into hour. to convert minutes into hour we divide by 60 because 1 hour = 60 minutes
![\frac{20}{60} =\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B60%7D%20%3D%5Cfrac%7B1%7D%7B3%7D)
so time = 1/3 and distance = 16
Average speed = distance by time
![speed =\frac{16}{\frac{1}{3} } =\frac{48}{1}= 48](https://tex.z-dn.net/?f=speed%20%3D%5Cfrac%7B16%7D%7B%5Cfrac%7B1%7D%7B3%7D%20%7D%20%3D%5Cfrac%7B48%7D%7B1%7D%3D%2048)
Average speed is 48 km per hour
Answer:
160 total beads
Step-by-step explanation:
so if 1/4 of the beads are red, then 3/4 of them are not.....so 3/4 is the remainder of beads.....and 3/5 of the remainder are yellow....so 3/5 of 3/4 =
3/5 * 3/4 = 9/20...so 9/20 are yellow.....and the rest (48) are blue.
1/4 + 9/20 = 5/20 + 9/20 = 14/20 reduces to 7/10...so 7/10 of the beads are red and yellow
so if 7/10 of the beads are red and yellow, then 3/10 are blue
3/10 of what number is 48
3/10x = 48
x = 48 * 10/3
x = 480/3
x = 160
let me check it..
1/4 are red......160 total beads.....so red beads = (1/4 * 160) = 160/4 = 40
3/5 of the remainder is yellow.....so 3/5 of (160 - 40) = 3/5(120) = 72 yellow
and then u have 48 blue...
40 + 72 + 48 = 160
so there are 160 total beads.......40 red, 72 yellow, and 48 blue <===
