Question

A scientist 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?

Answer 1

The rover would travel 75.95 centimeters in 15 1/2 seconds.

Explanation:

Simply multiply 4.9 by 15 1/2.

Hope it helps!

Answer 2

75.95 cm

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
