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

107 m
Step-by-step explanation:
Step 1:
Here the microscope magnifies by 10 times.
The initial length is 10.7 m
Step 2:
Let the object be magnified by 10 times . Then, 10 × 10.7 = 107
The answer is right because 12^2 + 35^2 = 1369 and 37^2 = 1369 1369=1369 so it is a right triangle
