Answer:
[tex]Speed = 2519.58 mph[/tex]
Step-by-step explanation:
Given
[tex]Distance = 6417.5km[/tex]
[tex]Time = 1\ hr: 35\ mins[/tex]
Required
Calculate the speed in miles per hour
Convert distance to miles
[tex]Distance = 6417.5km[/tex]
[tex]Distance = \frac{6417.5km}{1.609}\ miles[/tex]
[tex]Distance = 3988.50217526\ miles[/tex]
[tex]Time = 1\ hr: 35\ mins[/tex]
Divide minutes by 60
[tex]Time = 1\ hr + 35/60[/tex]
[tex]Time = 1\ hr + 0.583\ hr[/tex]
[tex]Time = 1.583hr[/tex]
The speed is:
[tex]Speed = Distance/Time[/tex]
[tex]Speed = 3988.50217526/1.583 mph[/tex]
[tex]Speed = 2519.58 mph[/tex]
