Step-by-step explanation:
If Abe rode for 77mins
Let ta represent Amil time and tb represent Abe time.
Then tb=77mins
The rate if amil is faster than able
Let the speed of mail be Va and that of Abel be Vb
Therefore Va>Vb
Velocity = distance / time
Amil rate Va=d/ta
If Amil rode 15miles
Da = 15miles
ta= 55mins
Since they are on the same track then the rate of Amil is
Va=Da/ta
Va= 15/55
Va= 0.273miles/minutes
Since they are on the same track they will have the same speed Da.
Vb= 15/77
Vb= 0.195miles/minutes

Answer:
Bearing of R from S = S 45° E or 135°
The bearing of R from Q
= S 66.42° w or 246.42°
Step-by-step explanation:
Distance between R and S
RS²= RP²+PS²
RS²= 15²+15²
RS²=225+225
RS= √450
RS= 21.21
Angle at S
21.21= 15/sins
Sin s= 15/21.21
S= sin^-1 15/21.21.
S= 45°
90+45= 135°
Bearing of R from S = S 45° E or 135°
Distance between R and Q
RQ²= PQ²+PR²
RQ²= 35²+15²
RQ²=1225+225
RQ= √1450
RQ= 38.08
RQ= 15/sinQ
SinQ= 15/38.08
SinQ= 0.40
Q=23.58°
90-23.58 = 66.42°
66.42+180= 246.42°
The bearing of R from Q
= S 66.42° w or 246.42°
All you need to do is 8 divided by 6. When you do so you get: 1.3 which could also be written as 1 3/8.
So each person gets 1 whole piece and 3/8 of another piece.
Answer:
18/14 or 1 2/7
Step-by-step explanation:
13/14 - 2/14(1/7) = 11/14
11/14 + 7/14(1/2) = 18/14
