Question

Car À moves at a speed of 8m/s for 43 seconds. Car B moves at a speed of 7 m/s for 50 seconds. Which car traveled a longer distance

Please show working

Answer 1

Distance = (speed) x (time)

Car A: Distance = (8 m/s) x (43 s) = 344 meters

Car B: Distance = (7 m/s) x (50 s) = 350 meters

350 meters is a longer distance than 344 meters.

Car-B traveled a longer distance than Car-A did.

Answer 2

`\boxed {\boxed {\sf Car \ B : 350 \ meters }}`

Step-by-step explanation:

Distance is equal to the product of speed and time.

`d=s*t`

1. Car A

Car A has a speed of 8 meters per second and travels for 43 seconds.

`s= 8 \ m/s \\t= 43 \ s`

Substitute the values into the formula.

`d= 8 \ m/s *43 \ s`

Multiply and note that the seconds will cancel out.

`d= 8 \ m*43= 344 \ m`

2. Car B

Car B has a speed of 7 meters per second and travels for 50 seconds.

`s= 7 \ m/s \\t= 50 \ s`

Substitute the values in and multiply.

`d= 7 \ m/s * 50 \ s`

`d= 7 \ m * 50 = 350 \ m`

350 meters is a longer distance than 344 meters, so Car B traveled the longer distance.
