Please show working

Answer 1

Answer:

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

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.

Answer 2

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.
