Question

The ship leaves at 18 40 to sail to the next port.

It sails 270 km at an average speed of 32.4 km/h
Find the time when the ship arrives.

Answer 1

32.4 - 27.0 = 5.4

18.40 + 54 =

7hrs:34mins

The ship arrived at

7:34pm

Answer 2

Explanation:

Given:

t₁ = 18:40 or 18 h 40 min

S = 270 km

V = 32.4 km/h

____________

t₂ - ?

Ship movement time:

t = S / V = 270 / 32.4 ≈ 8.33 h = 8 h 20 min

t₂ = t₁ + t = 18 h 40 min + 8 h 20 min

40 min + 20 min = 60 min = 1 h

18 h +8 h = 26 h = 24 h + 2 h

2 h + 1 h = 3 h

t₂ = 3:00

The ship will arrive at the destination port at 3:00 the next day.
