Answer 1

Step-by-step explanation:

Given Question:-

a car travels at a speed of X + 30 km and one hour, where X is a known find x if this car covers 300 km in 3 hour.?

Given:-

A car travels at a speed of (X+30) km/hr

and the car covers 300 km in 3 hours.

To find:-

Find the value of X?

Solution:-

The speed of the car=(X+30) km/hr

Distance covered by the car=300 kms

Time taken for the journey =3 hours

we know that

Distance =speed×time

=>300=(X+30)×3

=>(X+30)×3=300

=>X+30=300/3

=>X+30=100

=>X=100-30

=>X=70

Answer:-

The value of X=70 km/hr

Check:-

Speed of the car=X+30=70+30=100km/hr

Speed =Distance/time

=>Speed=300/3=100km/hr

Verified the given relation

Used formulae:-

• Distance =Speed×Time
• Speed=Distance/Time
