Question

A car with a constant velocity of 22 m/s is driven for 6.8 s. How far did it travel? (v =∆ d/∆t)

A. 29 m
B. 154 m
C. 150 m
D. 3 m

Answer 1

Answer : The correct option is, (C) 150 m

Explanation : Given,

Velocity of car = 22 m/s

Time = 6.8 s

Formula used :

`v=(\Delta d)/(\Delta t)`

where,

v = velocity

`\Delta d` = change in distance

`\Delta t` = change in time

Now put all the given values in the above formula, we get:

`22m/s=(\Delta d)/(6.8s)`

`\Delta d=22m/s* 6.8s`

`\Delta d=149.6m\approx 150m`

Thus, the distance traveled by car is, 150 m

Answer 2

C. 150 m

Step-by-step explanation:

We know

`distance = speed*time`

time =6.8 s

velocity =
`22 (m)/(sec)`

So ,
`distance =22*6.8=149.6` ≈150 m
