Answer:
After 7 hours Tevin will catch Enrique
Step-by-step explanation:
We have given speed of Enrique is 20 mph
Tevin left traveling after 2 hours of Enrique
Speed of Tevin is 28 mph
When Tevin catches Enrique will cover same distance
Let Enrique is traveling for t hours
Then Tevin will travel for t-2 hours
We know that distance = speed × time
So 
t = 7 hours
So after 7 hours Tevin will catch Enrique
If you divided 4.736 ÷ 100 you have to find the times 100 is in 473, is 4 times, then you have to find how many times is 100 in 736, is 7 times, then you have 36 but this is not a entire number then you add a 0, 100 is 3 times in 360, now you have a 6, you add two zeros, 100 is six times in 600. 47,36 is the answer.
Using cross multiplication method,
x -12 -12x
x 2 2x
-24 -10x
Therefore,
=3(x-12)(x+2)
Answer:
His usual speed is 105 km/hr.
Step-by-step explanation:
Let his usually speed be s km/hr and the distance between the towns be d km. So we have the equations:
s = d/6
s - 15 = d / (6 + 1)
from the first equation:
d = 6s and from the second:
d = 7(s - 15)
Eliminating d we get:
6s = 7(s - 15)
7s - 105 = 6s
s = 105.
Answer:
40 miles a day
Step-by-step explanation:
The difference in fixed charge is $20; the difference in mileage charge is $0.50 per mile. So it will take $20/$0.50 = 40 miles for the extra mileage cost to eat up the savings in fixed cost. At that mileage, both companies will charge the same amount:
A: 90 + 0.30·40 = 102
B: 70 + 0.80·40 = 102
