no she does not because 102 minutes equals 1.7 and 65*2 = 130 which is more than 65 mph

Answer:

35.5 mph

Explanation:

We are given that Sally Leadfoot was pulled over on her way from Syracuse to Ithaca by an officer claiming she was speeding.

Speed limit =65 mph

Sally traveled distance 97 km in 102 minutes

We have to find the Sally's average speed in mph

Time =102 minutes

We know that 1 hour =60 minutes


102 minutes=(102)/(60)=1.7hours

We know that 1 km=0.621371

97 km=
0.621371 * 97=60.272987miles

Average speed =
(60.272987)/(1.7)=35.45 mph

Average speed of Sally's =35.5 mph

Hence, average speed of Sally is less than 65 mph .Therefore, she was not fast speeding and she deserves a ticket.
