Harry catches the train from Belfast to Dublin at 4pm. The average speed of the train is 70 mph and the distance between Belfast

finlep [7]

Answer:

$Arrival\ Time = 5:30\ pm$

Step-by-step explanation:

Given

$Current\ Time = 4pm$

$Speed = 70mph$

$Distance = 105miles$

Required

Determine the arrival time

First, we calculate the time taken from Belfast to Dublin using:

$Speed = \frac{Distance}{Time}$

Substitute values to the expression.

$70 = \frac{105}{Time}$

Cross Multiply

$70 * Time = 105$

$Time = \frac{105}{70}$

$Time = 1.5\ hour$

Arrival time is then calculated as:

$Arrival\ Time = Current\ Time + Time\ Taken$

$Arrival\ Time = 4pm + 1.5\ hour$

$Arrival\ Time = 5:30\ pm$
