Question

A car travels for 2 hours and covers a speed of 240km.how long will the car take to cover a distance of 600km at the same constant average speed

Answer 1

Find the speed of the car first by using the distance formula. 
d=rt
240=2r
r=120 km/hr
Now plug the rate or the speed into the equation.
d=rt
600=120t
t=5 hours
Hope this helps.
