Ascientist builds a mars rover that can travel 4.9 centimeters per second on flat ground. if the rover continues at the same rate, how many centimeters will it travel in 15 1/2 seconds?

75.95 cm

Step-by-step explanation:

We know that distance = rate  times time

d =rt

We know the rate = 4.9 cm/s

and time = 15 1/2 s = 15.5 s

Substituting these into d=rt

d = (4.9 cm/s) * 15.5 s = 75.95 cm

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
