iVinArrow [24]

Answer:

$10:02:24\ \text{pm}$

Step-by-step explanation:

d = Distance to travel = 880 miles

s = Average speed of the car = 65 mph

Time taken to cover the distance is

$t=\dfrac{d}{s}\\\Rightarrow t=\dfrac{880}{65}\\\Rightarrow t=\dfrac{176}{13}\ \text{h}=13.54\ \text{hours}$

Time the car stopped

$3\times 10+60=90\ \text{minutes}=1.5\ \text{hours}$

Total time of the journey

$13.54+1.5=15.04\ \text{hours}$

Converting $0.04\ \text{hours}$ to minutes

$0.04\times 60=2.4$

So, the total time taken for the journey is $15\ \text{hours and }2\ \text{minutes and }24\text{seconds}$

Time when they reach their destination

$7:30+15:2.4\approx 10:02:24\ \text{pm}$
