hour and 35 minutes. How fast is this in miles per hour?

Answer 1

`Speed = 2519.58 mph`

Explanation:

Given

`Distance = 6417.5km`

`Time = 1\ hr: 35\ mins`

Required

Calculate the speed in miles per hour

Convert distance to miles

`Distance = 6417.5km`

`Distance = (6417.5km)/(1.609)\ miles`

`Distance = 3988.50217526\ miles`

`Time = 1\ hr: 35\ mins`

Divide minutes by 60

`Time = 1\ hr + 35/60`

`Time = 1\ hr + 0.583\ hr`

`Time = 1.583hr`

The speed is:

`Speed = Distance/Time`

`Speed = 3988.50217526/1.583 mph`

`Speed = 2519.58 mph`
