Answer:
the least required speed is 103.88 km/h
Step-by-step explanation:
Data provided in the question:
Total distance = 270 km
Total time to reach = Time between 8 a.m and 11:15 a.m i.e 3.25 hours
Now,
For the distance of 110 km speed was 100 km/h
therefore, the time taken to cover 110 km =
=
= 1.1 hour
For another 43 km speed was 42 km/h
therefore, the time taken to cover 43 km =
=
= 1.0238 hours
Now,
The distance left to be covered = 270 - 110 - 43 = 117 km
Time left = 3.25 h - 1.1 h - 1.0238 h = 1.1262 h
Thus required speed =
= 103.88 km/h
Hence, the least required speed is 103.88 km/h
The probability would be 14 over 100.
We can tell this because by the table, the number 1 was rolled 14 total times. You can state the probability by expressing with the number of times rolled over total times rolled. Since it was rolled a total of 100 times, we are left with 14/100.

Answer:
m= -15
Step-by-step explanation:
-2(m-30)=-6m
-2m + 60 = -6m
4m = -60
m = - 15
