Answer:
Linear speed= V= 175.84 m/s
Step-by-step explanation:
A wheel with a radius of 7 inches is rotating at 4 revolutions per second.
Linear speed v = rw
r= radius
r= 7 inches
w= angular speed
W= 4rev/s
But one rev= 2π
W= 4*(2π)/s
W= 8π/s
V= rw
V=7*8*3.14
V= 175.84 m/s

Answer:
3:40 p.m.
Step-by-step explanation:
Add 74 minutes to 1:25 p.m.; the improperly formed result witll be 1:99 p.m.; to express this properly, add 1 hour to this time and subtract 60 minutes from it:
2:39 p.m. (time at which Avery gets off the bus)
If Avery walked 61 minutes to get home and we want to know what time she arrived, we add 61 minutes to 2:39 p.m., obtaining 2:100 p.m., which must in turn be re-written as 3:40 p.m.
Avery arrived home at 3:40 p.m.
Note: another way in which to do this problem is to add 74 minutes and 61 minutes, obtaining 135 minutes, and then adding 135 minutes to 1:25 p.m. and making the necessary adjustments to the result:
1:25 p.m. + 135 minutes = 1:160 p.m., or (recognizing that 120 min = 2 hours)
3:40 p.m.
