Answer:
For a=0.9876 and b=0.9887 mid point will be 0.98815
Step-by-step explanation:
We have given a = 0.9876 and b = 0.9887
And N = 2
We have to find the mid point
For finding mid point we know that formula
Midpoint , here we have given a=0.9876 and b = 0.9887
So midpoint will be
So for a=0.9876 and b=0.9887 mid point will be 0.98815
Answer:
The average speed of car is 67 kilometers per hour.
Step-by-step explanation:
Given that:
Distance travelled in one hour = 45 km
Distance travelled in next 2 hours = 78*2 = 156 km
Total distance = 45+156 = 201
Total time = 1+2 = 3 hours
Average speed of the car =
Average speed of the car =
Average speed of the car = 67 km/hr
Hence,
The average speed of car is 67 kilometers per hour.
