Question

A toy plane moves at a constant speed of 2m/s. How long will it travel a distance of 42 meters?

A. 21 sec
B. 24 sec
C. 84 sec
D. 210 sec

Answer 1

option A. 21 sec

Explanation:

Speed = the distance over the time

Given:

Speed = 2 m/s and distance = 42 m and time = t

So,

2 = 42/t

Solve for t

t = 42/2 = 21 sec.

The answer is option A. 21 sec
