Question 1

Speed / Time / Distance
60 DST

Distance =

Answer 1

D = S x T / 60

Question 2

Speed / Time / Distance
60 DST

Speed =

Answer 2

S = 60 x D / T

Question 3

Speed / Time / Distance
60 DST

Time =

Answer 3

T = 60 x D / S

Question 4

Speed / Time / Distance
60 DST

A boat is travelling at 10 knots. How far will it travel in 20 minutes?

Answer 4

D = S x T  / 60
D = 10 x 20 / 60
D = 200 / 60
D = 3.3 NM

Question 5

Speed / Time / Distance
60 DST

A boat travelling at 10 knots took 3 hours and 45 minutes to travel from point A to point B.

NOTE: convert hours to minutes

Answer 5

3 x 60 + 45 = 225 minutes

D = S x T / 60
D = 10 x 225 / 60
D = 2250 / 60
D = 37.5 NM

Question 6

Speed / Time / Distance
60 DST

A boat travelled 12 NM in 40 minutes. How fast was it travelling?

Answer 6

S = 60 x D / T
S = 60 x 12 / 40
S = 720 / 40
S = 18 knots

Question 7

Speed / Time / Distance
60 DST

A boat travelling at 15 knots has to travel 12 NM until it reaches its destination. How long will it take?

Answer 7

T = 60 x D / S
T = 60 x 12 / 15
T = 720 / 15
T = 48 minutes
