Answer 1

Answer:

225 meter

Step-by-step explanation:

speed =54km/h×5/18=15m/s

time =15seconds

distance (s)=speed ×time =15×15m.=225m.

Answer 2

Answer:

Hola, here is your answer mate;

A car covers a distance x while moving at 54 km per hour in 15 seconds. What is the value of x?

So , Distance = speed × time

First we convert the speed from km per hour to meter per second . Because we are doing calculation in SI .

54 km/ h = (54 ×1000)÷3600 = 15 m/s

Now by using the formula :

[Distance x = speed × time]

x = 15 m/s × 15 s

x = 225 m

thus,the distance covered by the car is 225 m.

hope helpful :)
