How much time does it take a trucker to deliver his shipment 480 km away travelling at an average speed of 120 km/hr?

kifflom [539]

Answer: time=4 hours

Explanation:

formula:

speed = $\frac{distance}{time}$

time = $\frac{distance}{speed}$

time= x

speed = 120km/hr

distance = 480 km

x = $\frac{480 km}{120km/hr\\}$

= $\frac{48km*hr}{12km}$

cut the zeros

and remove the signs

then

$\frac{48}{12}$ = 4

therefore, time taken to deliver the shipment by trucker is 4 hours
