Step-by-step explanation:
In the first part, he was travelling with twice the speed, or Vs, for distance
48 - d, for 2 hours.
speed = distance/time
distance = speed * time
First part :
48 - d = 2V * 2
⇒d + 4V = 48
Second part:
d = V * 2
⇒d = 2V
Substitute 2s for d in equation 1.
2s + 4s = 48
6s = 48
s = 8
The speed in the second part is 8 mph.
<u>The speed in the first part is 2s = 2(8) = 16</u>

Answer:
8:07 am
Step-by-step explanation:
It takes 9 minutes to walk from his house to the bus station. It then takes 92 minutes for the bus to travel from Birmingham to Coventry. After arriving, he takes 12 minutes to reach his workplace. This takes a total of 113 minutes.
9 + 92 + 12 = 113
Convert 113 minutes to hours and minutes.
113 - 60 = 53
1 hr and 53 min
He has to be at work by 10. Subtract the time it takes to get to his work by the time he has to get there.
10 - 1 hr = 9
9 - 53 min = 8:07
The latest time he can leave is 8:07.
