Question

Toy car in a science experiment covers 1.6 meters in half a second. If a the car travels at a steady speed, how far will it go in 10 seconds? A.. 0.8 m B.. 8 m C. 16 m D. 32 m

Answer 1

The answer is D. 32 m.

The simple equation that connects speed (v), time (t), and distance (d) can be expressed as:

`v= (d)/(t)` ⇒
`d=v*t`

It is given:

`v = (1.6m)/(0.5s) = (1.6m*2)/(0.5s*2)= (3.2m)/(1s) = 3.2 m/s`
t = 10 s
d = ?

So:

`d= v*t=3.2m/s*10s = 32m`
