Answer 1

Answer:

317.52mi/hr..........

Answer 2

Hence the speed of the boat is 317.52 m/s

Explanation:

Distance covered = 1000 m

Time taken = 7.045 s

Convert distance to mile

1 mile = 1609.34 meters

1 meter = 1 / 1609.34 meters

1000 m = 1000 / 11609.34 miles

Convert time to hours

1 hour = 60 minutes x 60 seconds = 3600 seconds

1 second = 1 / 3600 hour

7.045 = 7.045 / 3600 hours

So speed of the boat = 1000 / 1609.34 ÷ 7.045 / 3600

Speed of the boat = 317.52 m/s

Hence the speed of the boat is 317.52 m/s
