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

a) 45 minutes

b)1.1 km per hour
