The distance between Town A and Town B is 45 kilometers.

a) If a train travels at a speed of 60 kilometers per hour, how long will it take to travel from Town A to Town B?

b) If a train takes 40 minutes to travel from Town A to Town B, what is its speed in kilometers per minute? Round your answer to 1 decimal place.

a)

0.8 hours

b)

1.1 kilometers/min

Step-by-step explanation:

a)

D = distance between town A and town B = 45 kilometers

v = speed of the train traveling from town A to town B = 60 kilometers per hour

t = time taken for the train to travel from town A to town B

Time taken is given as

t = D/v

inserting the values

t = 45/60

t = 0.8 hours

b)

D = distance between town A and town B = 45 kilometers

v = speed of the train traveling from town A to town B = ?

t = time taken for the train to travel from town A to town B = 40 minutes

Speed of the train is given as

v = D/t

inserting the values

v = 45/40

v = 1.1 kilometers/min

Answer: a) 45 minutes

b) 1.1 km per hour
