Do do this, you use the distance formula: time * speed = distance
So you do, 4.9 * 15.5 = 75.95
So, the rover will travel <u>75.95 centimeters</u> in 15.5 seconds at a speed of 4.9 cm./s
Idk this one REEE! i’m so sorry i can’t help :(
To solve this problem we first call x = number of action figures, y = number of dolles. A system of two equations with two unknowns must be made to describe the problem. The system is the following:
(x + 1) + y = 13
1/2 * x = y.
Then solving the system we have that x = 8 and y = 4.
Since we know that the number of action figures is twice as many dolls plus one, then x = 8 + 1 = 9.
Thus,
dollos = 4
action figures = 9
