Total distance = 380 miles
Let the time & distance of 1st day be = t1 & d1 respectively
Distance = Speed x Time
For second day : d2 = s2 x t2 ; d2 = 60 x t2
For first day : d1 = s1 x t1 ; d1 = 40 x t1
Given : d1 = d2 + 20 & t1 = t2 + 2 , putting these values in d1
d2 + 20 = 40 (t2 + 2)
Putting value of d2 ,
60 t2 + 20 = 40 t2 + 80
60 t2 - 40 t2 = 80 - 20
20t2 = 60
t2 = 60 / 20 ; t2 = 3
So, t1 = 3+2 = 5
Hence : d1 = 40 x 5 = 200 ; d2 = 60 x 3 = 180
Therefore , Total Distance = 200 + 180 = 380

Answer:
(a) and (b) are true
Step-by-step explanation:
a) is true.
b) is true. Replacing x with 8 in the equation y=1/4x-5 results in 2-5, or -3.
c) is false. See (a), above.
d) is false. Replacing x in the equation by 12 results in y = (1/4)(12) - 5, or -2.
1.
Convert 22 miles to feet.
1 mile = 5280 feet
22 × 5280 = 116,160 feet
2.
To convert this you divide the speed by 60 since there's 60 minutes in an hour
125/60 = 2.0833....
Since you round the answer would be
2.1 miles per minute
Answer:
the answer is
8:24
