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?
enter your answer in the box.

Step-by-step explanation:

distance = time * speed

4.9 =  1 second* speed

speed = 4.9/1 = 4.9 cm/sec

time = 15 1/2 = 31/2

distance = 31/2 *  4.9 = 75.95 cm

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
