Answer:
25.6 km/h
Step-by-step explanation:
Omani:
First, 1.5 hours = 1 hour and 30 minutes
and 66 miles = 105.6 km (66 x 1.6 = 105.6)
105.6 / 1.5 = 70.4 km/h
Omani's speed is 70.4 km/h
Adedi:
1 hour and 15 minutes is 1.25 hours
she drives 56 km in 1.25 hours
So 56 / 1.25 = 44.8 km/h
Adedi's speed is 44.8 km/h
Difference:
70.4 - 44.8 = 25.6 km/h
Omani is faster than Adedi with 25.6 km/h

Step-by-step explanation:
<span>The answer is 50.5.
Since X will consist of a random selection of the numbers from 1 to 100, the mean will be the middle of the set of numbers from 1 to 100 (so between 50 and 51). Imagine the set of whole numbers 1 to 100. To calculate the mean, we have to sum all the numbers, then divide by n=100. That gives 50,500/100= 50.5.</span>
