Answer:
a) 2.5 km
b) 1836 m ≈ 1.8 km (rounded)
Step-by-step explanation:
a) just add the two distances of the vertical and horizontal road. 900m + 1600m = 2500m = 2.5 km
b) Apply Pythagoras (a²+b²=c², where a and b are the vertical and horizontal roads, and c is the diagonal road).
c = √(1600²+900²) ≈ 1836m (rounded)
Answer:
133.06 miles per hour
Step-by-step explanation:
Distance =2438.9 miles
Time=18 hours 20 minutes.
First we convert the time to hour
60 minutes = 1 hour
20 minutes=(20/60) hour=0.33
Therefore her time=18+0.33 hour=18.33hour
We are to determine the average speed of her flight in miles per hour.
rate=distance/time
=2438.9/18.33
=133.06 miles per hour
Her average speed is 133.06 miles per hour
