trying to help my son, help on this: The distance a car travels is equal to the average speed times how long the car has traveled. Which equation should be used to find the speed ® of a car that averages traveling 100 miles in 1 ½ hours?

distance = speed / time speed = distance x time speed = 100 miles x 1.5 hours speed = 100 x ( 1.5 x 60 ) mins speed = 100 x (1.5 x 60 x 60 ) seconds = 540000 :)

ok so the expression would be r=(100)(1 1/2)

oh, i thought it wud be r=100/1 1/2

no because the Distance equation is Speed / time .. and they want to know what is the speed so, speed is Distance times time.. hmm i think this is correct
