The car is moving with a speed of 60km/hr.travels y km in x hours . Represent this situation as a linear equation of two variables Find the distance travelled when time 5 hours and also in 10 hours

Answer»

Answer:

Step-by-step explanation:

let the distance travelled in 5h and 10h be x & y respectively.

By UNITARY Method:

Time Taken (HOURS)                            Distance(km)

        1                                                       60

        5                                                        x

1/5 = 60/x

By CROSS MULTIPLICATION

x = 60x5

x = 300KM

--------------------------------------------------------------------------------------------

Time Taken (hours)                            Distance(km)

        1                                                       60

        10                                                        y

1/10 = 60/y

By cross multiplication

y = 60x10

y = 600km
