Answer:
2 hours
Step-by-step explanation:
Since Tory and Emilio's motorboats travel at the same speed, they are traveling at the speed of 30 km/h. Therefore, it should take Tory two hours to travel 60 km.
The probability is 0.1253.

Answer:
1/2n - 11 = -25
Hope this helps you! Have a good night!
Also, n = -28
1/2n - 11 = -25
1/2n - 11 + 11 = -25 + 11
1/2n = -14
1/2n / 1/2 = -14 / 1/2
n = -28
Check:
1/2(-28) - 11 = -25
-14 - 11 = -25
-25 = -25
Answer:
The car must move 48 km/h.
Step-by-Step Explanation
- Denote x km/h the speed of the car.
5*x km while the bus for 5 hours travel the distance:
5*30=150 km ,since the bus left 3 hours before the car its total distance from the car is 150+3*30=240 km. The car overtake the bus when 5*x=240 where x=48 km/h.
