Parrain

Answer: = 757.75 / (19:15 - 9:15)

Step-by-step explanation:

Speed can be found by the formula:

= Distance / Time

Distance here is 757.75 miles.

Time here is:

= 7:15 pm - 9:15 am

Best to use 24 hour annotation:

= 19:15 - 9:15

Formula would therefore be:

= 757.75 / (19:15 - 9:15)

Answer would be:

= 757.75 / (19:15 - 9:15)

= 75.78 mph
